Oops. Indeed. TASK_RUNNING isn't a bit at all, it's a lack of sleep.
Turning the logic the other way around:
/* Ignore processes that are dead or stopped (except for SIGKILL) */ mask = TASK_ZOMBIE | TASK_DEAD; if (sig != SIGKILL) mask != TASK_STOPPED;
and testing for !((p)->state & mask) should fix it. The mask ends up being the states that are _not_ good to send signals for ;)
