From 0e568536d94256819f17662c26c82a42e44a7a7c Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 4 Feb 2008 23:44:24 -0800 Subject: [PATCH] [MIPS] Use find_task_by_vpid in system calls There are some places left in mips, that lookup task in initial namespace, while the code doing so gets the pid from the user space and thus must treat it as virtual.
