This series is a quick re-spin of the v2 sent yesterday to address review
feedback from Chris. In particular, we now set EXEC_ASYNC on the trivial
batch and I deleted the syncobj cache. Somehow, when I was working on this
yesterday, I got it into my head that the kernel deduplicates syncobj
handles and that we needed a cache to handle them correctly. This is not
true. Every call to SYNCOBJ_FD_TO_HANDLE produces a new handle and the
kernel does the reference counting for us.
