The helper does a simple translation from block group flags to index to the btrfs_raid_array table. There's no apparent reason to inline the function, the translation happens usually once per function and is not called in a loop. Making it a proper function saves quite some binary code (x86_64, release config): text data bss dec hex filename 1164011 19253 14912 1198176 124860 pre/btrfs.ko 1161559 19253 14912 1195724 123ecc post/btrfs.ko DELTA: -2451 Also add the const attribute as there are no side effects, this could help compiler to optimize a few things without the function body.

btrfs_search_slot is called in multiple places in dir-item.c to search for a dir entry, and then calling btrfs_match_dir_name to return a btrfs_dir_item. In order to reduce the number of callers of btrfs_search_slot, create a common function that looks for the dir key, and if found call btrfs_match_dir_item_name. Signed-off-by:

After calling btrfs_search_slot is a common practice to check if the slot found isn't bigger than number of slots in the current leaf, and if so, search for the same key in the next leaf by calling btrfs_next_leaf, which calls btrfs_next_old_leaf to do the job. Calling btrfs_next_item in the same situation would end up in the same code flow, since * btrfs_next_item * btrfs_next_old_item * if slot >= nritems(curr_leaf) btrfs_next_old_leaf Change btrfs_verify_dev_extents and calculate_emulated_zone_size functions to use btrfs_next_leaf in the same situation.

Currently all the callers of btrfs_find_all_roots() pass a value of false for its ignore_offset argument. This makes the argument pointless and we can remove it and make btrfs_find_all_roots() always pass false as the ignore_offset argument for btrfs_find_all_roots_safe(). So just do that. Reviewed-by:

During a fast fsync, if we have already fsynced the file before and in the current transaction, we can make the inode item update more efficient and avoid acquiring a write lock on the leaf's parent. To update the inode item we are always using btrfs_insert_empty_item() to get a path pointing to the inode item, which calls btrfs_search_slot() with an "ins_len" argument of 'sizeof(struct btrfs_inode_item) + sizeof(struct btrfs_item)', and that always results in the search taking a write lock on the level 1 node that is the parent of the leaf that contains the inode item. This adds unnecessary lock contention on log trees when we have multiple fsyncs in parallel against inodes in the same subvolume, which has a very significant impact due to the fact that log trees are short lived and their height very rarely goes beyond level 2. Also, by using btrfs_insert_empty_item() when we need to update the inode item, we also end up splitting the leaf of the existing inode item when the leaf has an amount of free space smaller than the size of an inode item. Improve this by using btrfs_seach_slot(), with a 0 "ins_len" argument, when we know the inode item already exists in the log. This avoids these two inefficiencies. The following script, using fio, was used to perform the tests: $ cat fio-test.sh #!/bin/bash DEV=/dev/nvme0n1 MNT=/mnt/nvme0n1 MOUNT_OPTIONS="-o ssd" MKFS_OPTIONS="-d single -m single" if [ $# -ne 4 ]; then echo "Use $0 NUM_JOBS FILE_SIZE FSYNC_FREQ BLOCK_SIZE" exit 1 fi NUM_JOBS=$1 FILE_SIZE=$2 FSYNC_FREQ=$3 BLOCK_SIZE=$4 cat <<EOF > /tmp/fio-job.ini [writers] rw=randwrite fsync=$FSYNC_FREQ fallocate=none group_reporting=1 direct=0 bs=$BLOCK_SIZE ioengine=sync size=$FILE_SIZE directory=$MNT numjobs=$NUM_JOBS EOF echo "performance" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor echo echo "Using config:" echo cat /tmp/fio-job.ini echo echo "mount options: $MOUNT_OPTIONS" echo umount $MNT &> /dev/null mkfs.btrfs -f $MKFS_OPTIONS $DEV mount $MOUNT_OPTIONS $DEV $MNT fio /tmp/fio-job.ini umount $MNT The tests were done on a physical machine, with 12 cores, 64G of RAM, using a NVMEe device and using a non-debug kernel config (the default one from Debian). The summary line from fio is provided below for each test run. With 8 jobs, file size 256M, fsync frequency of 4 and a block size of 4K: Before: WRITE: bw=28.3MiB/s (29.7MB/s), 28.3MiB/s-28.3MiB/s (29.7MB/s-29.7MB/s), io=2048MiB (2147MB), run=72297-72297msec After: WRITE: bw=28.7MiB/s (30.1MB/s), 28.7MiB/s-28.7MiB/s (30.1MB/s-30.1MB/s), io=2048MiB (2147MB), run=71411-71411msec +1.4% throughput, -1.2% runtime With 16 jobs, file size 256M, fsync frequency of 4 and a block size of 4K: Before: WRITE: bw=40.0MiB/s (42.0MB/s), 40.0MiB/s-40.0MiB/s (42.0MB/s-42.0MB/s), io=4096MiB (4295MB), run=99980-99980msec After: WRITE: bw=40.9MiB/s (42.9MB/s), 40.9MiB/s-40.9MiB/s (42.9MB/s-42.9MB/s), io=4096MiB (4295MB), run=97933-97933msec +2.2% throughput, -2.1% runtime The changes are small but it's possible to be better on faster hardware as in the test machine used disk utilization was pretty much 100% during the whole time the tests were running (observed with 'iostat -xz 1'). The tests also included the previous patch with the subject of: "btrfs: avoid unnecessary log mutex contention when syncing log". So they compared a branch without that patch and without this patch versus a branch with these two patches applied. Reviewed-by:Josef Bacik <josef@toxicpanda.com> Signed-off-by:

One of the last steps of syncing the log is to remove all log contexts from the root's list of contexts, done at btrfs_remove_all_log_ctxs(). There we iterate over all the contexts in the list and delete each one from the list, and after that we call INIT_LIST_HEAD() on the list. That is unnecessary since at that point the list is empty. So just remove the INIT_LIST_HEAD() call. It's not needed, increases code size (bloat-o-meter reported a delta of -122 for btrfs_sync_log() after this change) and increases two critical sections delimited by log mutexes. Reviewed-by:

When syncing the log we acquire the root's log mutex just to update the root's last_log_commit. This is unnecessary because: 1) At this point there can only be one task updating this value, which is the task committing the current log transaction. Any task that enters btrfs_sync_log() has to wait for the previous log transaction to commit and wait for the current log transaction to commit if someone else already started it (in this case it never reaches to the point of updating last_log_commit, as that is done by the committing task); 2) All readers of the root's last_log_commit don't acquire the root's log mutex. This is to avoid blocking the readers, potentially for too long and because getting a stale value of last_log_commit does not cause any functional problem, in the worst case getting a stale value results in logging an inode unnecessarily. Plus it's actually very rare to get a stale value that results in unnecessarily logging the inode. So in order to avoid unnecessary contention on the root's log mutex, which is used for several different purposes, like starting/joining a log transaction and starting writeback of a log transaction, stop acquiring the log mutex for updating the root's last_log_commit.

When using the NO_HOLES feature and expanding the size of an inode, we update the inode's last_trans, last_sub_trans and last_log_commit fields at maybe_insert_hole() so that a fsync does know that the inode needs to be logged (by making sure that btrfs_inode_in_log() returns false). This happens for expanding truncate operations, buffered writes, direct IO writes and when cloning extents to an offset greater than the inode's i_size. However the way we do it is racy, because in between setting the inode's last_sub_trans and last_log_commit fields, the log transaction ID that was assigned to last_sub_trans might be committed before we read the root's last_log_commit and assign that value to last_log_commit. If that happens it would make a future call to btrfs_inode_in_log() return true. This is a race that should be extremely unlikely to be hit in practice, and it is the same that was described by commit bc0939fc ("btrfs: fix race between marking inode needs to be logged and log syncing"). The fix would simply be to set last_log_commit to the value we assigned to last_sub_trans minus 1, like it was done in that commit. However updating these two fields plus the last_trans field is pointless here because all the callers of btrfs_cont_expand() (which is the only caller of maybe_insert_hole()) always call btrfs_set_inode_last_trans() or btrfs_update_inode() after calling btrfs_cont_expand(). Calling either btrfs_set_inode_last_trans() or btrfs_update_inode() guarantees that the next fsync will log the inode, as it makes btrfs_inode_in_log() return false. So just remove the code that explicitly sets the inode's last_trans, last_sub_trans and last_log_commit fields. Reviewed-by:

In commit 351cbf6e ("btrfs: use nofs allocations for running delayed items") we wrapped all btree updates when running delayed items with memalloc_nofs_save() and memalloc_nofs_restore(), due to a lock inversion detected by lockdep involving reclaim and the mutex of delayed nodes. The problem is because the ref verify tool does some memory allocations with GFP_KERNEL, which can trigger reclaim and reclaim can trigger inode eviction, which requires locking the mutex of an inode's delayed node. On the other hand the ref verify tool is called when allocating metadata extents as part of operations that modify a btree, which is a problem when running delayed nodes, where we do btree updates while holding the mutex of a delayed node. This is what caused the lockdep warning. Instead of wrapping every btree update when running delayed nodes, change the ref verify tool to never do GFP_KERNEL allocations, because: 1) We get less repeated code, which at the moment does not even have a comment mentioning why we need to setup the NOFS context, which is a recommended good practice as mentioned at Documentation/core-api/gfp_mask-from-fs-io.rst 2) The ref verify tool is something meant only for debugging and not something that should be enabled on non-debug / non-development kernels; 3) We may have yet more places outside delayed-inode.c where we have similar problem: doing btree updates while holding some lock and then having the GFP_KERNEL memory allocations, from the ref verify tool, trigger reclaim and trying again to acquire the same lock through the reclaim path. Or we could get more such cases in the future, therefore this change prevents getting into similar cases when using the ref verify tool. Curiously most of the memory allocations done by the ref verify tool were already using GFP_NOFS, except a few ones for no apparent reason. Reviewed-by:

When we insert the delayed items of an inode, which corresponds to the directory index keys for a directory (key type BTRFS_DIR_INDEX_KEY), we do the following: 1) Pick the first delayed item from the rbtree and insert it into the fs/subvolume btree, using btrfs_insert_empty_item() for that; 2) Without releasing the path returned by btrfs_insert_empty_item(), keep collecting as many consecutive delayed items from the rbtree as possible, as long as each one's BTRFS_DIR_INDEX_KEY key is the immediate successor of the previously picked item and as long as they fit in the available space of the leaf the path points to; 3) Then insert all the collected items into the leaf; 4) Release the reserve metadata space for each collected item and release each item (implies deleting from the rbtree); 5) Unlock the path. While this is much better than inserting items one by one, it can be improved in a few aspects: 1) Instead of adding items based on the remaining free space of the leaf, collect as many items that can fit in a leaf and bulk insert them. This results in less and larger batches, reducing the total amount of time to insert the delayed items. For example when adding 100K files to a directory, we ended up creating 1658 batches with very variable sizes ranging from 1 item to 118 items, on a filesystem with a node/leaf size of 16K. After this change, we end up with 839 batches, with the vast majority of them having exactly 120 items; 2) We do the search for more items to batch, by iterating the rbtree, while holding a write lock on the leaf; 3) While still holding the leaf locked, we are releasing the reserved metadata for each item and then deleting each item, keeping a write lock on the leaf for longer than necessary. Releasing the delayed items one by one can take a significant amount of time, because deleting them from the rbtree can often be a bit slow when the deletion results in rebalancing the rbtree. So change this so that we try to create larger batches, with a total item size up to the maximum a leaf can support, and by unlocking the leaf immediately after inserting the items, releasing the reserved metadata space of each item and releasing each item without holding the write lock on the leaf. The following script that runs fs_mark was used to test this change: $ cat test.sh #!/bin/bash DEV=/dev/nvme0n1 MNT=/mnt/nvme0n1 MOUNT_OPTIONS="-o ssd" MKFS_OPTIONS="-m single -d single" FILES=1000000 THREADS=16 FILE_SIZE=0 echo "performance" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor umount $DEV &> /dev/null mkfs.btrfs -f $MKFS_OPTIONS $DEV mount $MOUNT_OPTIONS $DEV $MNT OPTS="-S 0 -L 5 -n $FILES -s $FILE_SIZE -t 16" for ((i = 1; i <= $THREADS; i++)); do OPTS="$OPTS -d $MNT/d$i" done fs_mark $OPTS umount $MNT It was run on machine with 12 cores, 64G of ram, using a NVMe device and using a non-debug kernel config (Debian's default config).

When extent tree gets corrupted, normally it's not extent tree root, but one toasted tree leaf/node. In that case, rescue=ibadroots mount option won't help as it can only handle the extent tree root corruption. This patch will enhance the behavior by: - Allow fill_dummy_bgs() to ignore -EEXIST error This means we may have some block group items read from disk, but then hit some error halfway. - Fallback to fill_dummy_bgs() if any error gets hit in btrfs_read_block_groups() Of course, this still needs rescue=ibadroots mount option. With that, rescue=ibadroots can handle extent tree corruption more gracefully and allow a better recover chance. Reported-by:

At reada_for_search(), when attempting to readahead a node or leaf's siblings, we skip the readahead of the siblings if the node/leaf is already in memory. That is probably fine for the READA_FORWARD and READA_BACK readahead types, as they are used on contexts where we end up reading some consecutive leaves, but usually not the whole btree. However for a READA_FORWARD_ALWAYS mode, currently only used for full send operations, it does not make sense to skip the readahead if the target node or leaf is already loaded in memory, since we know the caller is visiting every node and leaf of the btree in ascending order. So change the behaviour to not skip the readahead when the target node is already in memory and the readahead mode is READA_FORWARD_ALWAYS.

The highmem flag is used for allocating pages for compression and for raid56 pages. The high memory makes sense on 32bit systems but is not without problems. On 64bit system's it's just another layer of wrappers. The time the pages are allocated for compression or raid56 is relatively short (about a transaction commit), so the pages are not blocked indefinitely. As the number of pages depends on the amount of data being written/read, there's a theoretical problem. A fast device on a 32bit system could use most of the low memory pool, while with the highmem allocation that would not happen. This was possibly the original idea long time ago, but nowadays we optimize for 64bit systems. This patch removes all usage of the __GFP_HIGHMEM flag for page allocation, the kmap/kunmap are still in place and will be removed in followup patches. Remaining is masking out the bit in alloc_extent_state and __lookup_free_space_inode, that can safely stay. Signed-off-by: -

There used to be a patch in the original series for zoned support which limited the extent size to max_zone_append_size, but this patch has been dropped somewhere around v9. We've decided to go the opposite direction, instead of limiting extents in the first place we split them before submission to comply with the device's limits. Remove the related code, btrfs_fs_info::max_zone_append_size and btrfs_zoned_device_info::max_zone_append_size. This also removes the workaround for dm-crypt introduced in 1d68128c ("btrfs: zoned: fail mount if the device does not support zone append") because the fix has been merged as f34ee1dc ("dm crypt: Fix zoned block device support").

Pull mandatory file locking deprecation warning from Jeff Layton: "As discussed on the list, this patch just adds a new warning for folks who still have mandatory locking enabled and actually mount with '-o mand'. I'd like to get this in for v5.14 so we can push this out into stable kernels and hopefully reach folks who have mounts with -o mand. For now, I'm operating under the assumption that we'll fully remove this support in v5.15, but we can move that out if any legitimate users of this facility speak up between now and then" * tag 'locks-v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux: fs: warn about impending deprecation of mandatory locks
