From: John Stultz Date: Thu, 12 Mar 2015 17:23:40 +0000 (-0700) Subject: drm/amdkfd: Convert timestamping to use 64bit time accessors X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=affa7d86441a9fe1ddd67f4ed551ed41313da561;p=deliverable%2Flinux.git drm/amdkfd: Convert timestamping to use 64bit time accessors Convert the timestamping in the amdkfd driver to use a timespec64 and 64bit time accessors. Although the existing code is completely safe beyond y2038 because it deals with monotonic time, this patch is still needed in order to kill off all uses of struct timespec.
