If anyone has any objections, please let me know. ------------------ From: Deepak Rawat 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.
