fs: btrfs: fix false negatives in ROOT_ITEM search ROOT_ITEMs in btrfs are referenced without knowing their actual "offset" value. To perform these searches using only two items from the key, the btrfs driver uses a special "btrfs_search_tree_key_type" function. The algorithm used by that function to transform a 3-tuple search into a 2-tuple search was subtly broken, leading to items not being found if they were the first in their tree node. This commit fixes btrfs_search_tree_key_type to properly behave in these situations. Signed-off-by: Pierre Bourdon <delroth@gmail.com> Cc: Marek Behun <marek.behun@nic.cz>
