Subject: xen/blkfront: Add the CDROM_GET_CAPABILITY ioctl to blkfront.
X-Git-Tag: v2.6.27-rc1~1114^2~29
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=440a01a7f46742400c74d9d346118523e81d188b;p=pandora-kernel.git

xen/blkfront: Add the CDROM_GET_CAPABILITY ioctl to blkfront.

Return 0 instead of -EINVAL if the blkfront device is a cdrom,
i.e. had the VDISK_CDROM attribute.  This allows udev's cdrom_id
to correctly detect the device as a cdrom device.

[ Add blkif_ioctl, and CDROMMULTISESSION ]
