From 466877f2d25758e5ad007b292c1f225520f8c877 Mon Sep 17 00:00:00 2001 From: Deepak Rawat <drawat@vmware.com> Date: Mon, 26 Jun 2017 14:39:08 +0200 Subject: [PATCH] drm/vmwgfx: Free hash table allocated by cmdbuf managed res mgr Git-commit: 82fcee526ba8ca2c5d378bdf51b21b7eb058fe3a Patch-mainline: 4.12 References: bsc#1041744 commit 82fcee526ba8ca2c5d378bdf51b21b7eb058fe3a upstream. The hash table created during vmw_cmdbuf_res_man_create was never freed. This causes memory leak in context creation. Added the corresponding drm_ht_remove in vmw_cmdbuf_res_man_destroy. Tested for memory leak by running piglit overnight and kernel memory is not inflated which earlier was.
