Since btree_ptr_v2, we no longer require the journal seq blacklist table for skipping blacklisted bsets (btree node entries); the pointer to a given node indicates how much data is present. Therefore there's no longer any need for journal seq blacklist gc to walk the btree - we can prune entries older than journal last_seq. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
