Subject: [PATCH 1/5] KVM: Make the GET_SREGS and SET_SREGS ioctls symmetric
Date: Mon, 11 Dec 2006 10:15:13 -0000 [thread overview]
Message-ID: <20061211101513.C38EC2500CF@il.qumranet.com> (raw)
In-Reply-To: <457D2F6B.8070809@qumranet.com>
This makes the SET_SREGS ioctl behave symmetrically to the GET_SREGS
ioctl wrt the segment access rights flag.
