From 002e67454f61bb67d8071ac4d0cacb86a01d18e0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 9 Jan 2018 16:30:23 +0100 Subject: dma-direct: rename dma_noop to dma_direct The trivial direct mapping implementation already does a virtual to physical translation which isn't strictly a noop, and will soon learn to do non-direct but linear physical to dma translations through the device offset and a few small tricks. Rename it to a better fitting name.
