[Linaro-mm-sig] Re: [PATCH v3 1/6] dma-buf: Remove the signaled bit status check

Am 09.09.22 um 19:08 schrieb Arvind Yadav:

Remove the signaled bit status check because it is returning early when the fence is already signaled and __dma_fence_enable_signaling is checking the status of signaled bit again.
