Hi!
drivers/gpu/drm/drm_lock.c is the only remaining user of block_all_signals(): /* don't set the block all signals on the master process for now * really probably not the correct answer but lets us debug xkb * xserver for now */ if (!file_priv->is_master) { sigemptyset(&dev->sigmask); sigaddset(&dev->sigmask, SIGSTOP); sigaddset(&dev->sigmask, SIGTSTP); sigaddset(&dev->sigmask, SIGTTIN); sigaddset(&dev->sigmask, SIGTTOU); dev->sigdata.context = lock->context; dev->sigdata.lock = master->lock.hw_lock; block_all_signals(drm_notifier, dev, &dev->sigmask); }
Is this functionality still in use/needed? Otherwise we could get rid of block_all_signals() and unpuzzle the signaling code a bit. :-)
Thanks, //richard
