[lvm-devel] [PATCH] fix processing of %PVS arg in lvcreate



Fix lvcreate processing of %PVS argument.

- fix missing unlocking of VG
lvcreate -l 100%PVS -n lv1 vg_test
  Please specify physical volume(s) with %PVS
  Internal error: Volume Group vg_test was not unlocked

- if no PVS specified, use all available
