+Subject: [PATCH] xen-hvm: Allow disabling buffer
+
+commit f37f29d31488 "xen: slightly simplify bufioreq handling" hard
+coded setting req.count = 1 during initial field setup before the main
+loop.  This missed a subtltey that an early exit from the loop when
+there are no ioreqs to process, would have req.count == 0 for the return
+value.  Would handle_buffered_io() would then remove
+state->buffered_io_timer.  Instead handle_buffered_iopage() is basically
+always returning true and handle_buffered_io() always re-setting the timer.
+
+Restore the disabling of the timer by introducing a new handled_ioreq
+boolean and use as the return value.  The named variable will more
+clearly show the intent of the code.
