Pavel Emelyanov 60347f6716 pid namespaces: prepare proc_flust_task() to flush entries from multiple proc trees ... The first part is trivial - we just make the proc_flush_task() to operate on arbitrary vfsmount with arbitrary ids and pass the pid and global proc_mnt to it. The other change is more tricky: I moved the proc_flush_task() call in release_task() higher to address the following problem. When flushing task from many proc trees we need to know the set of ids (not just one pid) to find the dentries' names to flush. Thus we need to pass the task's pid to proc_flush_task() as struct pid is the only object that can provide all the pid numbers. But after __exit_signal() task has detached all his pids and this information is lost. This creates a tiny gap for proc_pid_lookup() to bring some dentries back to tree and keep them in hash (since pids are still alive before __exit_signal()) till the next shrink, but since proc_flush_task() does not provide a 100% guarantee that the dentries will be flushed, this is OK to do so.
