Subject: [PATCH v6 6/6] mips/kvm: Use ENOIOCTLCMD to indicate unimplemented ioctls.
Date: Thu, 23 May 2013 09:49:10 -0700	[thread overview]
Message-ID: <1369327750-28580-7-git-send-email-ddaney.cavm@gmail.com> (raw)
In-Reply-To: <1369327750-28580-1-git-send-email-ddaney.cavm@gmail.com>

From: David Daney <david.daney@cavium.com>

The Linux Way is to return -ENOIOCTLCMD to the vfs when an
unimplemented ioctl is requested.  Do this in kvm_mips instead of a
random mixture of -ENOTSUPP and -EINVAL.
