From 1d251d90080a2721e97550973ab5efe772bc56bf Mon Sep 17 00:00:00 2001 From: Yong Zhao Date: Wed, 4 Mar 2020 12:38:59 -0500 Subject: [PATCH] drm/amdkfd: Consolidate duplicated bo alloc flags ALLOC_MEM_FLAGS_* used are the same as the KFD_IOC_ALLOC_MEM_FLAGS_*, but they are interweavedly used in kernel driver, resulting in bad readability. For example, KFD_IOC_ALLOC_MEM_FLAGS_COHERENT is not referenced in kernel, and it functions implicitly in kernel through ALLOC_MEM_FLAGS_COHERENT, causing unnecessary confusion. Replace all occurrences of ALLOC_MEM_FLAGS_* with KFD_IOC_ALLOC_MEM_FLAGS_* to solve the problem.
