When we move a file into a directory with compression flag, we need to inherite BTRFS_INODE_COMPRESS and clear BTRFS_INODE_NOCOMPRESS as well. But if we move a file into a directory without compression flag, we need to clear both of them. It is the way how our setflags deals with compression flag, so keep the same behaviour here.

If a file has 3 small extents: | ext1 | ext2 | ext3 | Running "btrfs fi defrag" will only defrag the last two extents, if those extent mappings hasn't been read into memory from disk. This bug was introduced by commit 17ce6ef8 ("Btrfs: add a check to decide if we should defrag the range") The cause is, that commit looked into previous and next extents using lookup_extent_mapping() only. While at it, remove the code that checks the previous extent, since it's sufficient to check the next extent. Signed-off-by:

I removed this in an earlier commit and I was wrong. Because compression can return from filemap_fdatawrite() without having actually set any of it's pages as writeback() it can make filemap_fdatawait() do essentially nothing, and then we won't find any ordered extents because they may not have been created yet. So not only does this make fsync() completely useless, but it will also screw up if you truncate on a non-page aligned offset since we zero out the end and then wait on ordered extents and then call drop caches. We can drop the cache before the io completes and then we try to unpin the extent we just wrote we won't find it and everything goes sideways. So fix this by putting it back and put a giant comment there to keep me from trying to remove it in the future. Thanks, Signed-off-by:

A user reported lots of problems using compression on the new code and it turns out part of the problem was that igrab() was failing when we added a new ordered extent. This is because when writing out an inode under compression we immediately return without actually doing anything to the pages, and then in another thread at some point down the line actually do the ordered dance. The problem is between the point that we start writeback and we actually add the ordered extent we could be trying to reclaim the inode, which makes igrab() return NULL. So we need to do an igrab() when we create the async extent and then drop it when we are done with it. This makes sure we stay pinned in memory until the ordered extent can get a reference on it and we are good to go. With this patch we no longer panic in btrfs_finish_ordered_io().

Because btrfs can remove the device that was mounted we need to have a ->show_devname so that in this case we can print out some other device in the file system to /proc/mount. So if there are multiple devices in a btrfs file system we will just print the device with the lowest devid that we can find. This will make everything consistent and deal with device removal properly. The drawback is if you mount with a device that is higher than the lowest devicd it won't show up as the mounted device in /proc/mounts, but this is a small price to pay. This was inspired by Miao Xie's patch. Thanks, Reviewed-by:

Al pointed out that we can just toss out the old name on a device and add a new one arbitrarily, so anybody who uses device->name in printk could possibly use free'd memory. Instead of adding locking around all of this he suggested doing it with RCU, so I've introduced a struct rcu_string that does just that and have gone through and protected all accesses to device->name that aren't under the uuid_mutex with rcu_read_lock(). This protects us and I will use it for dealing with removing the device that we used to mount the file system in a later patch. Thanks, Reviewed-by:

I was getting hung on umount when a transaction was aborted because a range of one of the free space inodes was still locked. This is because the nocow stuff doesn't unlock anything on error. This fixed the problem and I verified that is what was happening. Thanks, Signed-off-by:

So we're forcing the eb's to have their ref count set to 1 so invalidatepage works but this breaks lots of things, for example root nodes, and is just plain wrong, we don't need to just evict all of this stuff. Also drop the invalidatepage altogether and add a page_cache_release(). With this patch we no longer hang when trying to access the root nodes after an aborted transaction and we no longer leak memory. Thanks, Signed-off-by:

If a transaction commit fails we don't abort it so we don't set an error on the file system. This patch fixes that by actually calling the abort stuff and then adding a check for a fs error in the transaction start stuff to make sure it is caught properly. Thanks, Signed-off-by:

I was getting lots of hung tasks and a NULL pointer dereference because we are not cleaning up the transaction properly when it aborts. First we need to reset the running_transaction to NULL so we don't get a bad dereference for any start_transaction callers after this. Also we cannot rely on waitqueue_active() since it's just a list_empty(), so just call wake_up() directly since that will do the barrier for us and such. Thanks, Signed-off-by:

The transaction abort stuff was throwing warnings from the list debugging code because we do a list_del_init outside of the delayed_refs spin lock. The delayed refs locking makes baby Jesus cry so it's not hard to get wrong, but we need to take the ref head mutex to make sure it's not being processed currently, and so if it is we need to drop the spin lock and then take and drop the mutex and do the search again. If we can take the mutex then we can safely remove the head from the list and carry on. Now when the transaction aborts I don't get the list debugging warnings. Thanks, Signed-off-by:

While doing my enospc work I got a transaction abortion that resulted in a panic when we tried to unlock_page() an already unlocked page. This is because we aren't calling extent_clear_unlock_delalloc with the locked page so it was unlocking all the pages in the range. This is wrong since __extent_writepage expects to have the page locked still unless we return *page_started as 1. This should keep us from panicing. Thanks, Signed-off-by:

TEAC's UD-H01 (and probably other devices) have a gap in the interface number allocation of their descriptors: Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 220 bNumInterfaces 3 [...] Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 [...] Interface Association: bLength 8 bDescriptorType 11 bFirstInterface 2 bInterfaceCount 2 bFunctionClass 1 Audio bFunctionSubClass 0 bFunctionProtocol 32 iFunction 4 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 2 bAlternateSetting 0 [...] Once a configuration is selected, usb_set_configuration() walks the known interfaces of a given configuration and calls find_iad() on each of them to set the interface association pointer the interface is included in. The problem here is that the loop variable is taken for the interface number in the comparison logic that gathers the association. Which is fine as long as the descriptors are sane. In the case above, however, the logic gets out of sync and the interface association fields of all interfaces beyond the interface number gap are wrong. Fix this by passing the interface's bInterfaceNumber to find_iad() instead. Signed-off-by:

To make sense of the tree mod log, the backref walker not only needs btrfs_search_old_slot, but it also called btrfs_next_leaf, which in turn was calling btrfs_search_slot. This obviously didn't give the correct result. This commit adds btrfs_next_old_leaf, a drop-in replacement for btrfs_next_leaf with a time_seq parameter. If it is zero, it behaves exactly like btrfs_next_leaf. If it is non-zero, it will use btrfs_search_old_slot with this time_seq parameter. Signed-off-by:

get_old_root could race with root node updates because we weren't locking the node early enough. Use btrfs_read_lock_root_node to grab the root locked in the very beginning and release the lock as soon as possible (just like btrfs_search_slot does). Signed-off-by:

When resolving indirect refs, we used to call btrfs_next_leaf in case we didn't find an exact match. While we should find exact matches most of the time, in case we don't, we must continue searching. Treating those matches differently depending on the level we're searching doesn't make sense. Even worse, we might end up searching for a key larger than the largest, in which case there is no next_leaf and subsequent jobs would fail. This commit drops the bogous lines. Signed-off-by:

A bunch of bugzillas have complained how noisy the nmi_watchdog is during boot-up especially with its expected failure cases (like virt and bios resource contention). This is my attempt to quiet them down and keep it less confusing for the end user. What I did is print the message for cpu0 and save it for future comparisons. If future cpus have an identical message as cpu0, then don't print the redundant info. However, if a future cpu has a different message, happily print that loudly.
