Xen devel - Apr 2008 - [PATCH] [RFC] scrub pages when balloon frees them

When a domain is killed, all its memory pages are cleared. However, I
looked at the code path that is run when a domain releases memory from
the balloon and could not find code that would scrub these pages. So I
added this line, but I am wondering whether previously it was forgotten
or not done due to some other reason?

The domain is responsible for scrubbing its own secrets while it is alive.
