From f9b67f0014cba18f1aabb6fa9272335a043eb6fd Mon Sep 17 00:00:00 2001 From: Logan Gunthorpe Date: Wed, 19 Apr 2017 13:36:10 -0600 Subject: dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro Seeing the kunmap_atomic dma_buf_ops share the same name with a macro in highmem.h, the former can be aliased if any dma-buf user includes that header. I'm personally trying to include highmem.h inside scatterlist.h and this breaks the dma-buf code proper. Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP. To maintain consistency I've renamed all four of kmap* and kunmap* to be map* and unmap*. (Even though only kmap_atomic presently conflicts.)
