Subject: osd/PrimaryLogPG: add condition "is_chunky_scrub_active" to check object in chunky_scrub.
X-Git-Tag: v13.0.1~426^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=6c81c9bb0979c101c112e8ccd45880e08bfdb945;p=ceph-ci.git

osd/PrimaryLogPG: add condition "is_chunky_scrub_active" to check object in chunky_scrub.

Avoid every time call scrubber.write_block_by_scrub. Most time scrubber
is inactive. And compare to write_block_by_scrub, is_chunky_scrub_active
is light.
