move_ratelimit() now has a bool that specifies whether we want to wait for copygc to finish. When copygc is running, we're probably low on free buckets instead of consuming the remaining buckets, we want to wait for copygc to finish. This should help with performance, and run away bucket fragmentation. Signed-off-by: Daniel Hill <daniel@gluo.nz> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
