[Xen-devel] [PATCH] [xentop] fix abnormal value cpu(%) when domain shutdown.
Hi,
This patch intends to fix the xentop cpu(%).
If we test multiple domain create/shutdown many times.
sometimes abnormal values of cpu(%) are appeared.
This is because shutdown domain remove failure.
(in other words, memory corruption of struct )
This corruption makes abnormal cpu(%) values are shown xentop
sometimes.
