bcachefs: Rewrite journal_seq_blacklist machinery Now, we store blacklisted journal sequence numbers in the superblock, not the journal: this helps to greatly simplify the code, and more importantly it's now implemented in a way that doesn't require all btree nodes to be visited before starting the journal - instead, we unconditionally blacklist the next 4 journal sequence numbers after an unclean shutdown.
