The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was removed as of v6.8-rc1, so it became a dead flag since the commit 16a1d968 ("mm/slab: remove mm/slab.c and slab_def.h"). And the series[1] went on to mark it obsolete to avoid confusion for users. Here we can just remove all its users, which has no functional change.

Currently we ignore s_clusters_per_group field in the on-disk superblock if bigalloc feature is not enabled. However e2fsprogs don't even open the filesystem if s_clusters_per_group is invalid. This results in an odd state where kernel happily works with the filesystem while even e2fsck refuses to touch it. Verify that s_clusters_per_group is valid even if bigalloc feature is not enabled to make things consistent. Due to current e2fsprogs behavior it is unlikely there are filesystems out in the wild (except for intentionally fuzzed ones) with invalid s_clusters_per_group counts.

We observed a corruption during on-line resize of a file system that is larger than 16 TiB with 4k block size. With having more then 2^32 blocks resize_inode is turned off by default by mke2fs. The issue can be reproduced on a smaller file system for convenience by explicitly turning off resize_inode. An on-line resize across an 8 GiB boundary (the size of a meta block group in this setup) then leads to a corruption: dev=/dev/<some_dev> # should be >= 16 GiB mkdir -p /corruption /sbin/mke2fs -t ext4 -b 4096 -O ^resize_inode $dev $((2 * 2**21 - 2**15)) mount -t ext4 $dev /corruption dd if=/dev/zero bs=4096 of=/corruption/test count=$((2*2**21 - 4*2**15)) sha1sum /corruption/test # 79d2658b39dcfd77274e435b0934028adafaab11 /corruption/test /sbin/resize2fs $dev $((2*2**21)) # drop page cache to force reload the block from disk echo 1 > /proc/sys/vm/drop_caches sha1sum /corruption/test # 3c2abc63cbf1a94c9e6977e0fbd72cd832c4d5c3 /corruption/test 2^21 = 2^15*2^6 equals 8 GiB whereof 2^15 is the number of blocks per block group and 2^6 are the number of block groups that make a meta block group. The last checksum might be different depending on how the file is laid out across the physical blocks. The actual corruption occurs at physical block 63*2^15 = 2064384 which would be the location of the backup of the meta block group's block descriptor. During the on-line resize the file system will be converted to meta_bg starting at s_first_meta_bg which is 2 in the example - meaning all block groups after 16 GiB. However, in ext4_flex_group_add we might add block groups that are not part of the first meta block group yet. In the reproducer we achieved this by substracting the size of a whole block group from the point where the meta block group would start. This must be considered when updating the backup block group descriptors to follow the non-meta_bg layout. The fix is to add a test whether the group to add is already part of the meta block group or not.

When ext4 is mounted without journal, with discard mount option, and on a device not supporting trim, we print error for each and every freed extent. This is not only useless but actively harmful. Instead ignore the EOPNOTSUPP error. Trim is only advisory anyway and when the filesystem has journal we silently ignore trim error as well.

When allocating EA inode, quota accounting is done just before ext4_xattr_inode_lookup_create(). Logically these two operations belong together so just fold quota accounting into ext4_xattr_inode_lookup_create(). We also make ext4_xattr_inode_lookup_create() return the looked up / created inode to convert the function to a more standard calling convention.

When yangerkun review commit 93cdf49f ("ext4: Fix best extent lstart adjustment logic in ext4_mb_new_inode_pa()"), it was found that the best extent did not completely cover the original request after adjusting the best extent lstart in ext4_mb_new_inode_pa() as follows: original request: 2/10(8) normalized request: 0/64(64) best extent: 0/9(9) When we check if best ex can be kept at start of goal, ac_o_ex.fe_logical is 2 less than the adjusted best extent logical end 9, so we think the adjustment is done. But obviously 0/9(9) doesn't cover 2/10(8), so we should determine here if the original request logical end is less than or equal to the adjusted best extent logical end. In addition, add a comment stating when adjusted best_ex will not cover the original request, and remove the duplicate assertion because adjusting lstart makes no change to b_ex.fe_len.

This may lead to filesystem corruption. To ensure filesystem consistent when errors=remount-ro there is need to call ext4_handle_error() to abort journal.

If one group is marked as block bitmap corrupted, its free blocks cannot be used and its free count is also deducted from the global sbi->s_freeclusters_counter. User might be confused about the absent free space because we can't query the information about corrupted block groups except unreliable error messages in syslog. So add a hint to show block bitmap corrupted groups in mb_groups.

If the file was opened and never read the close will pass a NULL pointer to hrtime_cancel(). - Rewrite of eventfs. Linus wrote a patch series to remove the dentry references in the eventfs_inode and to use ref counting and more of proper VFS interfaces to make it work. - Add warning to put_ei() if ei is not set to free. That means something is about to free it when it shouldn't. - Restructure the eventfs_inode to make it more compact, and remove the unused llist field. - Remove the fsnotify*() funtions for when the inodes were being created in the lookup code. It doesn't make sense to notify about creation just because something is being looked up. - The inode hard link count was not accurate. It was being updated when a file was looked up. The inodes of directories were updating their parent inode hard link count every time the inode was created. That means if memory reclaim cleaned a stale directory inode and the inode was lookup up again, it would increment the parent inode again as well. Al Viro said to just have all eventfs directories have a hard link count of 1.
