[Xen-devel] Question about scrub_heap_pages

[조현권 <chkwon91@xxxxxxxxx>]

Hi I am studying xen memory setup

I am wondering the job of scrub heap pages in setup_mm

If i see the code, it clear unallocated page by setting them to 0 using memset instruction

But it looks unneccessary assuming unallocated page will be written to valid data when it is qllocated

Is there special reason?
