[PATCH] Console blanking locking fix
I've had WARN_CONSOLE_UNLOCKED warnings when calling TIOCLINUX TIOCL_BLANKSCREEN and TIOCL_UNBLANKSCREEN. (I'm blind and I use a braille display. I use those functions to blank my laptop's screen so people don't read it, and hopefully to conserve power.) The warnings are from these places: do_blank_screen at drivers/char/vt.c:2754 (Not tainted) save_screen at drivers/char/vt.c:575 (Not tainted) do_unblank_screen at drivers/char/vt.c:2822 (Not tainted) set_palette at drivers/char/vt.c:2908 (Not tainted) At a glance I would think the following patch ought to fix that. Tested on one machine. Could you please tell me if this is correct and/or forward the patch where appropriate...
