[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. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Cc: "Eric W.
