An assorted set of optimizations and cleanups related to io trees.
Details in the change logs.

Filipe Manana (22):
  btrfs: remove duplicate error check at btrfs_clear_extent_bit_changeset()
  btrfs: exit after state split error at btrfs_clear_extent_bit_changeset()
  btrfs: add missing error return to btrfs_clear_extent_bit_changeset()
  btrfs: use bools for local variables at btrfs_clear_extent_bit_changeset()
  btrfs: avoid extra tree search at btrfs_clear_extent_bit_changeset()
  btrfs: simplify last record detection at btrfs_clear_extent_bit_changeset()
  btrfs: remove duplicate error check at btrfs_convert_extent_bit()
  btrfs: exit after state split error at btrfs_convert_extent_bit()
  btrfs: exit after state insertion failure at btrfs_convert_extent_bit()
  btrfs: avoid unnecessary next node searches when clearing bits from extent range
  btrfs: avoid repeated extent state processing when converting extent bits
  btrfs: avoid researching tree when converting bits in an extent range
  btrfs: simplify last record detection at btrfs_convert_extent_bit()
  btrfs: exit after state insertion failure at set_extent_bit()
  btrfs: exit after state split error at set_extent_bit()
  btrfs: simplify last record detection at set_extent_bit()
  btrfs: avoid repeated extent state processing when setting extent bits
  btrfs: avoid researching tree when setting bits in an extent range
  btrfs: remove unnecessary NULL checks before freeing extent state
  btrfs: don't BUG_ON() when unpinning extents during transaction commit
  btrfs: remove variable to track trimmed bytes at btrfs_finish_extent_commit()
  btrfs: make extent unpinning more efficient when committing transaction
