    SubjectRe: [PATCH] [6/13] Core maskable allocator
    Hi, Andi,

    As I dig through this patch, I find it mostly makes sense; seems like it
    could be a good idea. I did have one little API question...

    > +struct page *
    > +alloc_pages_mask(gfp_t gfp, unsigned size, u64 mask)
    > +{
    > + unsigned long max_pfn = mask >> PAGE_SHIFT;

    The "mask" parameter isn't really a mask - it's an upper bound on the
    address of the allocated memory. Might it be better to call it
    "max_addr" or "limit" or "ceiling" or some such so callers understand
    for sure how it's interpreted? The use of the term "mask" throughout
    the interface could maybe create a certain amount of confusion.
