-Subject: [PATCH] present: Only requeue for next MSC after flip failure
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This code was added to deal with the driver present hook failing, in
-which case we need to wait for the next MSC before executing the
-presentation.
-
-However, it could also take effect in cases where the driver incorrectly
-thinks the current MSC matches the target one (e.g. due to the kernel
-interface only supporting 32-bit MSC values), in which case it could
-result in the presentation getting requeued over and over.
-
-To prevent such issues, check specifically for the target MSC
-immediately following the current MSC.
