bcachefs: Faster checking for missing journal entries
Previously, we would do a linear search over journal entry gaps, checking for entries that aren't actually missing beacuse the sequence number was blacklisted. But multi device filesystems can have massive gaps in journal entry sequence numbers, and the linear search then becomes quite painful. Fix this with two new helpers for iterating over the blacklist table: bch2_journal_seq_next_blacklisted() bch2_journal_seq_next_nonblacklisted() Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
