| H A D | pid.h | 1a657f78 Mon Oct 02 04:18:59 CDT 2006 Oleg Nesterov <oleg@tv-sign.ru> [PATCH] introduce get_task_pid() to fix unsafe get_pid()
proc_pid_make_inode:
ei->pid = get_pid(task_pid(task));
I think this is not safe. get_pid() can be preempted after checking "pid
!= NULL". Then the task exits, does detach_pid(), and RCU frees the pid.
