bcachefs: Copygc now uses backpointers Previously, copygc needed to walk the entire extents & reflink btrees to find extents that needed to be moved. Now that we have backpointers, this patch implements bch2_evacuate_bucket() in the move code, which copygc now uses for evacuating mostly empty buckets. Also, thanks to the new backpointers code, copygc can now move btree nodes. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
