Well. Half of it has gone so far ;) > > Attaching meminfo and sysrq-m after fillmem. (I meant a really big fillmem: a couple of 2GB ones. Not to worry.) It's not in slab and the pagecache and anonymous memory stuff seems to be working OK. So it has to be something else, which does a bare __alloc_pages(). Low-level block stuff, networking, arch code, perhaps. I don't think I've ever really seen code to diagnose this. A simplistic approach would be to add eight or so ulongs into struct page, populate them with builtin_return_address(0...7) at allocation time, then modify sysrq-m to walk mem_map[] printing it all out for pages which have page_count() > 0. That'd find the culprit. - 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/
