The patch titled
SLUB: consolidate trace code
has been removed from the -mm tree. Its filename was
slub-consolidate-trace-code.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: SLUB: consolidate trace code
From: Christoph Lameter <clameter@xxxxxxx>
Trace in both slab_alloc and slab_free has a lot of common code. Use a single
function for both.
