  "message": "tty: restore locked ioctl file op\n\nRestore tty locked ioctl handler which was replaced with\nan unlocked ioctl handler in hung_up_tty_fops by the patch:\n\ncommit e10cc1df1d2014f68a4bdcf73f6dd122c4561f94\nAuthor: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nDate:   Thu May 10 22:22:50 2007 -0700\n\n    tty: add compat_ioctl\n\nThis was reported in:\n[Bug 8473] New: Oops: 0010 [1] SMP\n\nThe bug is caused by switching to hung_up_tty_fops in do_tty_hangup.  An\nioctl call can be waiting on BLK after testing for existence of the locked\nioctl handler in the normal tty fops, but before calling the locked ioctl\nhandler.  If a hangup occurs at that point, the locked ioctl fop is NULL\nand an oops occurs.\n\n(akpm: we can remove my debugging code from do_ioctl() now, but it\u0027ll be OK to\ndo that for 2.6.23)\n\nSigned-off-by: Paul Fulghum \u003cpaulkf@microgate.com\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
