The patch titled
attach_pid() with struct pid parameter
has been removed from the -mm tree. Its filename was
attach_pid-with-struct-pid-parameter.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: attach_pid() with struct pid parameter
From: Sukadev Bhattiprolu <[EMAIL PROTECTED]>
Implement a new version of attach_pid() with a struct pid parameter and wrap
find_attach_pid() around it. attach_pid() would also be used in subsequent
container patches.
