Subject: os/bluestore: ref ovec for CLONE, CLONERANGE
X-Git-Tag: v10.1.0~113^2~1
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=19e6b643f0158cfadbc858e412c5e3d27c041180;p=ceph.git

os/bluestore: ref ovec for CLONE, CLONERANGE

This keeps ovec up to date.  Marginally more efficient.
