Subject: ioctl32: Unknown cmd

	Hi Arnd, Jens,

The recent (post 2.6.23) changes to compat_ioctl made the reporting of
unsupported ioctls more verbose. E.g. on the PS3 I get:

| ioctl32(cdrom_id:608): Unknown cmd fd(3) cmd(00005331){t:'S';sz:0} arg(00000000) on /dev/.tmp-11-0
| ioctl32(hdparm:1427): Unknown cmd fd(3) cmd(0000031f){t:03;sz:0} arg(00000000) on /dev/ps3da
| ioctl32(hdparm:1427): Unknown cmd fd(3) cmd(0000031f){t:03;sz:0} arg(00000000) on /dev/ps3da

The first one is triggered by the detection of the CD/DVD/BD-ROM driver,
The others are triggered by me running hdparm.

Was this intentional?

With kind regards,
