The patch titled
SLUB: Simplify dma index -> size calculation
has been removed from the -mm tree. Its filename was
slub-simplify-dma-index-size-calculation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: SLUB: Simplify dma index -> size calculation
From: Christoph Lameter <clameter@xxxxxxx>
There is no need to caculate the dma slab size ourselves. We can simply
lookup the size of the corresponding non dma slab.
