Hi Christian, David, For timeline semaphore we need points to signaled in order. I'm struggling to understand how this fence-chain implementation preserves ordering of the seqnos. One of the scenario I can see an issue happening is when you have a timeline with points 1 & 2 and userspace subm

[PATCH 02/11] dma-buf: add new dma_fence_chain container v4

From: Christian König Lockless container implementation similar to a dma_fence_array, but with only two elements per node and automatic garbage collection. v2: properly document dma_fence_chain_for_each, add dma_fence_chain_find_seqno, drop prev reference during garbage collection if it's no
