+Subject: [PATCH] iris: implement inter-context busy-tracking
+
+Previously, no buffers were ever marked as EXEC_OBJECT_ASYNC so the
+Kernel would ensure dependency tracking for us. After we implemented
+explicit busy tracking in commit 89a34cb8450a, only the external
+objects kept relying on the Kernel's implicit tracking and Iris did
+inter-batch busy tracking, meaning we lost inter-screen and
+inter-context synchronization. This seemed fine to me since, as far as
+I understood, it is the duty of the application to synchronize itself
+against multiple screens and contexts.
+
+The problem here is that applications were actually relying on the old
+behavior where the Kernel guarantees synchronization, so 89a34cb8450a
+can be seen as a regression. This commit addresses the inter-context
+synchronization case.
