[PATCH v2 0/3] btrfs: fix mmap writes for NOCOW files/extents

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

A bug fix and a couple cleanups. Details in the individual change logs.

V2: Fix a bug in patch 1/3 where if write_bytes < reserved_space we would
    exit without unlocking the cow lock, so set only_release_metadata to
    true before bailing out in that case.
    Added Qu's review tags.

Filipe Manana (3):
  btrfs: fix -ENOSPC mmap write failure on NOCOW files/extents
  btrfs: use variable for io_tree when clearing range in btrfs_page_mkwrite()
  btrfs: use btrfs_inode local variable at btrfs_page_mkwrite()
