[PATCH] fix TASK_STOPPED vs TASK_NONINTERACTIVE interaction
do_signal_stop:
for_each_thread(t) {
if (t->state < TASK_STOPPED)
++sig->group_stop_count;
}
However, TASK_NONINTERACTIVE > TASK_STOPPED, so this loop will not
count TASK_INTERRUPTIBLE | TASK_NONINTERACTIVE threads.
See also wait_task_stopped(), which checks ->state > TASK_STOPPED.

[ We really probably should always use the appropriate bitmasks to test
task states, not do it like this. Using something like
#define TASK_RUNNABLE (TASK_RUNNING | TASK_INTERRUPTIBLE | \
TASK_UNINTERRUPTIBLE | TASK_NONINTERACTIVE)
and then doing "if (task->state & TASK_RUNNABLE)" or similar. But the
ordering of the task states is historical, and keeping the ordering
does make sense regardless. ]
