The patch titled
SLUB: Use correct flags to check for DMA cache
has been removed from the -mm tree. Its filename was
slub-use-correct-flags-to-check-for-dma-cache.patch
This patch was dropped because it was folded into slub-core.patch
------------------------------------------------------
Subject: SLUB: Use correct flags to check for DMA cache
From: Christoph Lameter <clameter@xxxxxxx>
We use a GFP mask to check the SLAB flags if this is a DMA cache.
Fix this by using the correct SLAB mask and then use the SLUB_DMA for the
ORing of flags. If the system does not support DMA then we will OR zero
which will hopefully get the compiler to drop the useless if statement as
well.
