Subject: bcachefs: Fix hash_check_key()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=419fc65f8cfbadb29b2024457bf914787af8db91;p=linux.git

bcachefs: Fix hash_check_key()

On hash collision when we have to check for duplicates or incorrect
hash value, we weren't specifying a snapshot ID to iterate with.
