Hi,

Suppose I have a vma belonging to a user process and in its address range a
lot of pages are mapped.

What should I do if I want to set the data of all the page frames to zero,
without unmapping any of them or mapping any new pages?

Can zap_page_range / zap_vma_ptes do that? It seems zap functions would
unmap pages.

Thanks,
Cheng Quan
