Paul Fulghum 38ad2ed08d tty: restore locked ioctl file op ... Restore tty locked ioctl handler which was replaced with an unlocked ioctl handler in hung_up_tty_fops by the patch: commit e10cc1df1d Author: Paul Fulghum <paulkf@microgate.com> Date: Thu May 10 22:22:50 2007 -0700 tty: add compat_ioctl This was reported in: [Bug 8473] New: Oops: 0010 [1] SMP The bug is caused by switching to hung_up_tty_fops in do_tty_hangup. An ioctl call can be waiting on BLK after testing for existence of the locked ioctl handler in the normal tty fops, but before calling the locked ioctl handler. If a hangup occurs at that point, the locked ioctl fop is NULL and an oops occurs. (akpm: we can remove my debugging code from do_ioctl() now, but it'll be OK to do that for 2.6.23) Signed-off-by: Paul Fulghum <paulkf@microgate.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2007-06-16 13:16:15 -07:00
