Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable:
  Btrfs: use join_transaction in btrfs_evict_inode()
  Btrfs - use %pU to print fsid
  Btrfs: fix extent state leak on failed nodatasum reads
  btrfs: fix unlocked access of delalloc_inodes
  Btrfs: avoid stack bloat in btrfs_ioctl_fs_info()
  btrfs: remove 64bit alignment padding to allow extent_buffer to fit into one fewer cacheline
  Btrfs: clear current->journal_info on async transaction commit
  Btrfs: make sure to recheck for bitmaps in clusters
  btrfs: remove unneeded includes from scrub.c
  btrfs: reinitialize scrub workers
  btrfs: scrub: errors in tree enumeration
  Btrfs: don't map extent buffer if path->skip_locking is set
  Btrfs: unlock the trans lock properly
  Btrfs: don't map extent buffer if path->skip_locking is set
  Btrfs: fix duplicate checking logic
  Btrfs: fix the allocator loop logic
  Btrfs: fix bitmap regression
  Btrfs: don't commit the transaction if we dont have enough pinned bytes
  Btrfs: noinline the cluster searching functions
  Btrfs: cache bitmaps when searching for a cluster
