+Subject: [PATCH] vulkancts:
+
+O_TRUNC value in OperationId enum collides with the macro O_TRUNC
+defined in the POSIX header fnctl.h. To avoid the collision undefine
+O_TRUNC in this particular sourcefile before its is used in enums
+down below.
+
+This is fixed upstream differently
+https://github.com/KhronosGroup/VK-GL-CTS/commit/564c6062f72fe7ecd92b4aea1558c441e651c76b
+
+But until we get this module uprev'ed to that, lets use a simpler
+workaround
+
+Upstream-Status: Inappropriate [Fixed Differently]
