Hi,
I need to have a debug print for all pages belonging to a process, for which i have the following code:
if (task->mm && task->mm->mmap) { /* For all vma-s of a process */ for (vma = task->mm->mmap; vma!=NULL; vma = vma->next) { pgd = pgd_offset(mm, address); if (!pgd_present(*pgd)) continue;
pud = pud_offset(pgd, address); if (!pud_present(*pud)) continue;
pmd = pmd_offset(pud, address); if (!pmd_present(*pmd)) continue;
pte = pte_offset_map_lock (task->mm->vm_mm, pmd, address, &ptl);
print pte_pfn(*pte) and other debug info;
pte_unmap_unlock(pte, ptl); } }
The code hangs. I do not get anything in dmesg. Any pointers by observing the code?
