pte_dirty and PageDirty?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Does anyone know the difference between pte_dirty(pte)
and PageDirty(page)?

AFAIK each pte points to a page frame and should be
the same, but sometimes pte_dirty returns true and
PageDirty returns false for the same physical page
frame. Below is a snippet of code:

...
pfn = pte_pfn(pte);
if (pfn_valid(pfn)) {
	page = pfn_to_page(pfn);
        if pte_dirty(pte) {};
        if (PageDirty(page)) {};
        ...
}
...

Any idea???

BR,

Mauricio Lin.
