use get_user_pages, this function works on vma and pin pages in memory as well, typically used by filesystem Direct I/O implementation. Thanks, Rajat On Sun, Apr 17, 2011 at 9:34 AM, Park Chan ho <parkch98@gmail.com> wrote:

Hi all, I want to retrieve "struct page" pointer from vm_area_struct. How do I write code below example?

------------example code------------ struct task_struct *p; struct vm_area_struct *vma; struct page *page;

for_each_process(p) {    if (!p->mm) continue;    for (vma = p->mm->mmap; vma; vma = vma->vm_next) {       for (i = vma->vm_start; i < vma->vm_end; i += PAGE_SIZE) {            /* How to get page pointer? */            page = ???       }    } }
