From 064aebdef25abbc3e1d920375f87113825a02870 Mon Sep 17 00:00:00 2001 From: Yong Zhao Date: Wed, 1 Nov 2017 19:21:26 -0400 Subject: [PATCH 3379/4131] drm/amdkfd: Clean up the data structure in kfd_process A list of per-process queues is maintained in the kfd_process_queue_manager, so the queues array in kfd_process is redundant and in fact unused.
