Subject: ReplicatedPG: copy: add an ObjectContextRef to CopyOp
X-Git-Tag: v0.71~22^2~12
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=6ed8b7ae56d88c586e3d359e649b41b892d3cee1;p=ceph.git

ReplicatedPG: copy: add an ObjectContextRef to CopyOp

Use that instead of the OpContext::obc in copy codepaths.
