    Subject[RFC][patch 0/2] mm: remove PageReserved
    Hi,

    I'll be looking to send these off to Andrew after 2.6.14 opens,
    with the aim of having them merged by 2.6.15 hopefully.

    It doesn't look like they'll be able to easily free up a page
    flag for 2 reasons. First, PageReserved will probably be kept
    around for at least one release. Second, swsusp and some arch
    code (ioremap) wants to know about struct pages that don't point
    to valid RAM - currently they use PageReserved, but we'll probably
    just introduce a PageValidRAM or something when PageReserved goes.

    I believe this makes memory management cleaner and easier to
    understand. My other reason behind this is that the lockless
    pagecache patches needs it for sane page refcounting.

    If anyone has an issue with the patches or my merge plan, let's
    get some discussion going.

    Thanks,
    Nick
