Oleg Nesterov e17f8851e1 [PATCH] fill_tgid: fix task_struct leak and possible oops ...

1. fill_tgid() forgets to do put_task_struct(first).

2. release_task(first) can happen after fill_tgid() drops tasklist_lock,
   it is unsafe to dereference first->signal.

This is a temporary fix, imho the locking should be reworked.
