Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason:
"We've got corner cases for updating i_size that ceph was hitting,
error handling for quotas when we run out of space, a very subtle
snapshot deletion race, a crash while removing devices, and one
deadlock between subvolume creation and the sb_internal code (thanks
lockdep)."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
Btrfs: move d_instantiate outside the transaction during mksubvol
Btrfs: fix EDQUOT handling in btrfs_delalloc_reserve_metadata
Btrfs: fix possible stale data exposure
Btrfs: fix missing i_size update
Btrfs: fix race between snapshot deletion and getting inode
Btrfs: fix missing release of the space/qgroup reservation in start_transaction()
Btrfs: fix wrong sync_writers decrement in btrfs_file_aio_write()
Btrfs: do not merge logged extents if we've removed them from the tree
btrfs: don't try to notify udev about missing devices
