Prev: [PATCH -mm 4/6] powerpc: remove unnecessary sync_single_range_* in swiotlb_dma_ops
Next: [PATCH -mm 5/6] swiotlb: remove unnecessary swiotlb_sync_single_range_*
From: FUJITA Tomonori on 27 Apr 2010 08:30 sync_single_range_for_cpu and sync_single_range_for_device hooks are unnecessary because sync_single_for_cpu and sync_single_for_device can be used instead.
