Oleg Nesterov a593d6edeb [PATCH] proc: convert do_task_stat() to use lock_task_sighand() ... Drop tasklist_lock. ->siglock protects almost all interesting data (including sub-threads traversal) except: ->signal->tty protected by tty_mutex ->real_parent the task can't be unhashed while we are holding ->siglock, so ->real_parent can change from under us but we can safely dereference it under rcu_read_lock() ->pgrp/->session we can get inconsistent numbers if the task does sys_setsid/daemonize at the same time. I hope this is acceptable. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Cc: "Eric W.
