Hi Nirmoy, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on drm-intel/for-linux-next] [also build test WARNING on drm-exynos/exynos-drm-next tegra-drm/drm/tegra/for-next drm-tip/drm-tip linus/master v5.7-rc3 next-20200429] [cannot apply to drm/drm-next] [if you

[PATCH 1/1] drm/mm: optimize rb_hole_addr rbtree search in high addr mode

Userspace can severely fragment rb_hole_addr rbtree by manipulating alignment while allocating buffers. Fragmented rb_hole_addr rbtree would result in large delays while allocating buffer object for a userspace application. It takes long time to find suitable hole because if we fail to find a suita
