-  Skip pvmove of RAID, thin, snapshot, origin, or mirror LVs in a cluster.
   Refresh existing VG before autoactivation (event retrigger/device reappeared).
   Use pvscan -b in udev rules to avoid a deadlock on udev process count limit.
   Add pvscan -b/--background for the command to be processed in the background.
   Don't assume stdin file descriptor is readable.
   Avoid unlimited recursion when creating dtree containing inactive pvmove LV.
   Require exactly 3 arguments for lvm2-activation-generator. Remove defaults.
-  Disable pvmove of merging or converting logical volumes.
-  Enable pvmove of snapshots and snapshot origins.
-  Fix inability to specify LV name when pvmove'ing a RAID, mirror, or thin-LV.
   Inform lvmetad about any lost PV label to make it in sync with system state.
   Support most of lvchange operations on stacked thin pool meta/data LVs.
-  Add ability to pvmove RAID, mirror, and thin volumes.
