[Xen-devel] [PATCH] Add periodic fflush to xentop batch mode.

[Yusuke KANEKI <Kaneki.Yusuke@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Add periodic fflush to xentop(batch mode).

If you want to make monitor tool using the following command,
you can not get output every some seconds.

xentop -b -d 1 > xentop.log
(above tool use tail command to get periodic data from xentop.log)

This patch is useful when you get 
xentop output(batch mode) periodicaly using pipe.


Best Regards,
 Yusuke Kaneki
