Merge branch 'for-linus-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs updates from Chris Mason:
"This has a series of fixes and cleanups that Dave Sterba has been
collecting.
There is a pretty big variety here, cleaning up internal APIs and
fixing corner cases"
* 'for-linus-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (124 commits)
Btrfs: use the correct type when creating cow dio extent
Btrfs: fix deadlock between dedup on same file and starting writeback
btrfs: use btrfs_debug instead of pr_debug in transaction abort
btrfs: btrfs_truncate_free_space_cache always allocates path
btrfs: free-space-cache, clean up unnecessary root arguments
btrfs: convert btrfs_inc_block_group_ro to accept fs_info
btrfs: flush_space always takes fs_info->fs_root
btrfs: pass fs_info to (more) routines that are only called with extent_root
btrfs: qgroup: Move half of the qgroup accounting time out of commit trans
