[PATCH] scsi: allow persistent reservations without CAP_SYS_RAWIO

From: Paolo Bonzini
Date: Tue Jun 12 2012 - 12:08:39 EST


Persistent reservations commands cannot be issued right now without
giving CAP_SYS_RAWIO to the process who wishes to send them. This
is a bit heavy-handed, allow these two commands.
