Different versions differ on the size of the blacklist range; it is theoretically possible that we could end up with blacklisted journal sequence numbers newer than the newest seq we find in the journal, and pick a new start seq that's blacklisted. Explicitly check for this in bch2_fs_journal_start(). Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
