Subject: [PATCH 6/9] dma-buf/dma-fence: Allow wait_any_timeout without default_wait
Date: Tue,  8 Aug 2017 15:46:06 -0700	[thread overview]
Message-ID: <1502232369-19753-7-git-send-email-jason.ekstrand@intel.com> (raw)
In-Reply-To: <1502232369-19753-1-git-send-email-jason.ekstrand@intel.com>

dma_fence_wait_any_timeout only relies on two things to work correctly:

 1) The SIGNALED flag to be set upon fence signal
 2) The callback list to get called upon fence signal

Both of these are part of the core dma-fence API so it should work fine
even with a non-default wait function.
