--- Comment #2 from Emil Velikov emil.l.velikov@gmail.com --- Hi Guillaume
With args.fd used for output this seems like a false positive. Alternative solution would be to make Valgrind aware of this. A similar issue exists for args.handle in drmPrimeFDToHandle.
I fear that not many people keep track of bugzilla, so please forward your patch to the dri-devel mailing list [1].
Thanks Emil
