| H A D | taskstats.c | diff fca178c0c6e8d52a1875be36b070f30884ebfae9 Sat Oct 28 12:38:49 CDT 2006 Oleg Nesterov <oleg@tv-sign.ru> [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.
