From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> When building drm+i915 I get around 150 lines of sparse noise from dma_fence __rcu warnings. This series eliminates all of that. The first two patches were already posted by Chris, but there wasn't any real reaction, so I figured I'd repost with a wider Cc list. As for the other two patches, I'm no expert on dma_fence and I didn't spend a lot of time looking at it so I can't be sure I annotated all the accesses correctly. But I figured someone will scream at me if I got it wrong ;) Cc: Dave Airlie <airlied@xxxxxxxxxx> Cc: Jason Ekstrand <jason@xxxxxxxxxxxxxx> Cc: linaro-mm-sig@xxxxxxxxxxxxxxxx Cc: linux-media@xxxxxxxxxxxxxxx Cc: Alex Deucher <alexander.deucher@xxxxxxx> Cc: Christian König <christian.koenig@xxxxxxx> Cc: Sumit Semwal <sumit.semwal@xxxxxxxxxx> Cc: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Chris Wilson (2): drm/syncobj: Mark up the fence as an RCU protected pointer dma-buf/fence: Sparse wants __rcu on the object itself Ville Syrjälä (2): drm/syncobj: Use proper methods for accessing rcu protected pointers dma-buf: Use rcu_assign_pointer() to set rcu protected pointers drivers/dma-buf/reservation.c | 2 +- drivers/gpu/drm/drm_syncobj.c | 11 +++++++---- include/drm/drm_syncobj.h | 2 +- include/linux/dma-fence.h | 2 +- 4 files changed, 10 insertions(+), 7 deletions(-) -- 2.13.6
