Subject: qa/workunits/rbd: avoid unnecessary sleeping in stop_mirror()
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=f18fe5d15f72e34ab74b8ae187a47b52883fc780;p=ceph.git

qa/workunits/rbd: avoid unnecessary sleeping in stop_mirror()

There is no need to wait for anything if -KILL is passed for sig
because the process would disappear immediately.  In teuthology runs
where multiple rbd-mirror daemons are deployed (and therefore need to
be stopped when stop_mirrors() is called by the test), it causes
gratuitous delays of 4+ seconds.
