The patch titled
Uninline the task_xid_nr_ns() calls
has been removed from the -mm tree. Its filename was
uninline-the-task_xid_nr_ns-calls.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Uninline the task_xid_nr_ns() calls
From: Pavel Emelyanov <xemul@xxxxxxxxxx>
Since these are expanded into call to pid_nr_ns() anyway, it's OK to move
the whole routine out-of-line. This is a cheap way to save ~100 bytes from
vmlinux. Together with the previous two patches, it saves half-a-kilo from
the vmlinux.
Un-inline other (currently inlined) functions must be done with additional
performance testing.
