From 198fe21b0a17fe9c68cb519ecc566534b04f122b Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 18 Oct 2007 23:40:06 -0700 Subject: pid namespaces: helpers to find the task by its numerical ids When searching the task by numerical id on may need to find it using global pid (as it is done now in kernel) or by its virtual id, e.g. when sending a signal to a task from one namespace the sender will specify the task's virtual id and we should find the task by this value.
