Subject: [PATCH 11/12] mips: use find_task_by_vpid in system calls
Date: Tue, 29 Jan 2008 17:06:32 +0300 [thread overview]
Message-ID: <479F32E8.3090001@openvz.org> (raw)
In-Reply-To: <479F2C5C.1050303@openvz.org>
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.
