Unfortunately, the behaviour needed of lfs_dir_fetchwith is as subtle as it is important. When fetching from a block corrupted by power-loss, lfs_dir_fetch must be able to rewind any state it picks up to before the corruption. This is not limited to the directory state, but includes find results and other side-effects. This gets a bit complicated when trying to generalize littlefs's fetchwith mechanics. Being able to scan a directory block during a fetch greatly impacts the runtime of littlefs operations, but if the state is generic how do we know what to rollback to? The fix here is to leave the management of rolling back state to the fetchwith match functions, and transparently pass a CRC tag to indicate the temporary state can be saved.
