We need to check that the fragmentation/merging is occurring between the quiesce calls.

One of the suggested approaches is to use the corresponding asok command to precisely control when the quiescing begins:

    def test_quiesce_parent_frag(self):
        """ 
        """ 

        self._configure_subvolume()

        self.mount_a.run_shell_payload("for i in `seq 1 100`; do mkdir -p foo/$i; done")

        path_parent = self.mount_a.cephfs_mntpt + "/foo" 

        path_q1 = path_parent + "/1" 
        J = self.fs.rank_tell("quiesce", "path", path_q1)
        log.debug(f"{J}")
        reqid = self._reqid_tostr(J['op']['reqid'])
        self._wait_for_quiesce_complete(reqid)

        self.fs.rank_tell("dirfrag", "split", path_parent, "0/0", "1")

        path_q2 = path_parent + "/2" 
        J = self.fs.rank_tell("quiesce", "path", path_q2)
        log.debug(f"{J}")
        reqid = self._reqid_tostr(J['op']['reqid'])
        self._wait_for_quiesce_complete(reqid) # will fail without fix

        # TODO: verify dir is fragmented
