Subject: [PATCH 3/5] btrfs: handle ENOENT in btrfs_uuid_tree_iterate
Date: Fri,  6 Dec 2019 09:37:16 -0500	[thread overview]
Message-ID: <20191206143718.167998-4-josef@toxicpanda.com> (raw)
In-Reply-To: <20191206143718.167998-1-josef@toxicpanda.com>

If we get an -ENOENT back from btrfs_uuid_iter_rem when iterating the
uuid tree we'll just continue and do btrfs_next_item().  However we've
done a btrfs_release_path() at this point and no longer have a valid
path.  So increment the key and go back and do a normal search.
