Subject: osdc/Objecter: update op_target_t::paused in _calc_target
X-Git-Tag: v14.1.0~693^2
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=e7a23d86e0b90cfd91e7126f958c0501d537e280;p=ceph-ci.git

osdc/Objecter: update op_target_t::paused in _calc_target

LingerOp::target.paused has no chance to be touched by anyone (see Objecter::_send_linger),
then the following bug exists:

1. ceph osd pause
2. rados watch -p pool oid
3. ceph osd unpause
3. the linger op will be in a lost state, i.e., osd op cancelled and the linger
   op will not be resent

Fixes: http://tracker.ceph.com/issues/37398
