Subject:   osd/PG: add new have_unfound() function in MissingLoc
X-Git-Tag: v12.0.0~353^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=7d9fd21e79d2739315ad15802bffd156dbf1be4a;p=ceph.git

  osd/PG: add new have_unfound() function in MissingLoc
          No need to lookup all objects in needs_recovery_map if only want to
          know whether if there are unfound objects.
