[PATCH v2 0/2] btrfs: fix lost error value deleting root reference

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

Fix a silent failure in case deleting a root reference fails when searching
for an item. Then make btrfs_del_root_ref() less likely to run into such
type of bug in the future. Details in the changelogs.

V2: Fix patch 2/2. If the BTRFS_ROOT_BACKREF_KEY item is not found, but
    the BTRFS_ROOT_REF_KEY is found, then before we would return -ENOENT
    and now we were returning 0 (unless an error happened when deleting
    the BTRFS_ROOT_REF_KEY item). Just return -ENOENT whenever one of
    the items is not found, all the callers abort the transaction if
    btrfs_del_root_ref() returns an error.

Filipe Manana (2):
  btrfs: fix silent failure when deleting root reference
  btrfs: simplify error handling at btrfs_del_root_ref()
