Subject: wait_task_stopped/continued: remove unneeded p->signal != NULL check
X-Git-Tag: v2.6.24-rc1~703

wait_task_stopped/continued: remove unneeded p->signal != NULL check

The child was found on ->children list under tasklist_lock, it must have a
valid ->signal. __exit_signal() both removes the task from parent->children
and clears ->signal "atomically" under write_lock(tasklist).

Remove unneeded checks.
