Subject: OSD: add handlers for MOSDPG(Push|PushReply|Pull)
X-Git-Tag: v0.67-rc1~138^2~1^2~2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=c0bd831acee487a944392b73780e1d5dfe677553;p=ceph.git

OSD: add handlers for MOSDPG(Push|PushReply|Pull)

MOSDPG(Push|PushReply|Pull|SubOp|SubOpReply) need the
same thing checked prior to queueing the op, so they
share a templated handler.
