Re: [Linaro-mm-sig] [PATCH 00/19] [Set 2] Rid W=1 warnings from GPU

by Christian König

Well that's quite a patch set. First of all can you separate this a bit more by driver? I'm assuming we maintainers are supposed to pick that up and apply it. radeon and amdgpu can stick together since that is mostly Alex and me, but I'm not sure if we want to do some of the suggested changes to radeon. Going to pick up the single TTM change for upstreaming. Thanks, Christian.

[PATCH 1/2] mm: mmap: fix fput in error path v2

by Christian König

Patch "495c10cc1c0c CHROMIUM: dma-buf: restore args..." adds a workaround for a bug in mmap_region.

[PATCH 5.9 267/391] drm/shme-helpers: Fix dma_buf_mmap forwarding bug

by Greg Kroah-Hartman

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> commit f49a51bfdc8ea717c97ccd4cc98b7e6daaa5553a upstream. When we forward an mmap to the dma_buf exporter, they get to own everything. Unfortunately drm_gem_mmap_obj() overwrote vma->vm_private_data after the driver callback, wreaking the exporter complete. This was noticed because vb2_common_vm_close blew up on mali gpu with panfrost after commit 26d3ac3cb04d ("drm/shmem-helpers: Redirect mmap for imported dma-buf"). Unfortunately drm_gem_mmap_obj also acquires a surplus reference that we need to drop in shmem helpers, which is a bit of a mislayer situation. Maybe the entire dma_buf_mmap forwarding should be pulled into core gem code. Note that the only two other drivers which forward mmap in their own code (etnaviv and exynos) get this somewhat right by overwriting the gem mmap code. But they seem to still have the leak. This might be a good excuse to move these drivers over to shmem helpers completely.
