<div dir="ltr">Hi,<div><br></div><div>Suppose I have a vma belonging to a user process and in its address range a lot of pages are mapped.</div><div><br></div><div>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? </div>
<div><br></div><div>Can zap_page_range / zap_vma_ptes do that? It seems zap functions would unmap pages. </div><div><br></div><div>Thanks,</div><div>Cheng Quan</div></div>
