Date: Mon, 04 May 2009 13:29:22 +0400 From: Michael Tokarev <mjt@....msk.ru> To: Linux-kernel <linux-kernel@...r.kernel.org> Subject: compat ioctl32 for /dev/snapshot? Is there any reason why 32-bit uswsusp &Friends does not work on 64bits kernel? For one, 32bits s2disk produces the following when trying to suspend: ioctl32(s2disk:4134): Unknown cmd fd(4) cmd(400c330d){t:'3';sz:12} arg(ff853554) on /dev/snapshot ioctl32(s2disk:4134): Unknown cmd fd(4) cmd(4004330a){t:'3';sz:4} arg(00000805) on /dev/snapshot this is coming from: error = ioctl(dev, SNAPSHOT_SET_SWAP_AREA, &swap); if (error && !offset) error = ioctl(dev, SNAPSHOT_SET_SWAP_FILE, blkdev); but I guess (just guess!) that other SNAPSHOT_* operations will also fail the same way. Is there a reason why those are not in compat_ioctl?
