Subject: btrfs: return errors from btrfs_del_csums in cleanup_ref_head
From: Josef Bacik <josef@xxxxxxxxxxxxxx>
commit 856bd270dc4db209c779ce1e9555c7641ffbc88e upstream.
We are unconditionally returning 0 in cleanup_ref_head, despite the fact
that btrfs_del_csums could fail. We need to return the error so the
transaction gets aborted properly, fix this by returning ret from
btrfs_del_csums in cleanup_ref_head.
