 ====================================
+  Add existing report settings to lvm.conf.
   Use VG read lock during 'pvscan --cache -aay' autoactivation.
   Issue a VG refresh before autoactivation only if the PV has changed/is new.
   Add flag to lvmetad protocol to indicate the PV scanned has changed/is new.
