From 4f8232bbf887123f78bcdca3dfd2b3dfa52a0112 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 21 Feb 2020 12:24:02 -0800 Subject: dma-direct: remove the cached_kernel_address hook dma-direct now finds the kernel address for coherent allocations based on the dma address, so the cached_kernel_address hooks is unused and can be removed entirely.
