Subject: ReplicatedPG: _committed_pushed_object don't pass op
X-Git-Tag: v0.67-rc1~138^2~1^2~11
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=31e19a64b033ff6b96e27ebcd1953934c65f04bb;p=ceph.git

ReplicatedPG: _committed_pushed_object don't pass op

Add a separate callback to handle marking the event and
the stats.
