 PIPE_FLUSH_END_OF_FRAME: Whether the flush marks the end of frame.
 
 PIPE_FLUSH_DEFERRED: It is not required to flush right away, but it is required
-to return a valid fence. The behavior of fence_finish or any other call isn't
-changed. The only side effect can be that fence_finish will wait a little
-longer. No guidance is given as to how drivers should implement fence_finish
-with deferred flushes. If some drivers can't do deferred flushes safely, they
-should just ignore the flag.

+and the context is still unflushed, and the ctx parameter of fence_finish is
+equal to the context where the fence was created, fence_finish will flush
