Merge tag 'ceph-for-5.8-rc2' of git://github.com/ceph/ceph-client

Pull ceph fixes from Ilya Dryomov:
 "An important follow-up for replica reads support that went into -rc1
  and two target_copy() fixups"

* tag 'ceph-for-5.8-rc2' of git://github.com/ceph/ceph-client:
  libceph: don't omit used_replica in target_copy()
  libceph: don't omit recovery_deletes in target_copy()
  libceph: move away from global osd_req_flags
