Oh for gawd's sake. If you want to allocate a page from within the first 1/4 of a zone, and if all those pages are in use for something else then you'll need to run reclaim against the first 1/4 of that zone. Or fail the allocation. Or run reclaim against the entire zone. The second two options are self-evidently dumb. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
