  • b4fb37662   [PATCH] Page migration documentation update ... Browse Code »

    Update the documentation for page migration.

    - Fix up bits and pieces in cpusets.txt

    - Rework text in vm/page-migration to be clearer and reflect the final
    version of page migration in 2.6.16. Mention Andi Kleen's numactl
    package that contains user space tools for page migration via
    libnuma. Add reference to numa_maps and to the manpage in numactl.

    - Add todo list for outstanding issues

  • a48d07afd   [PATCH] Direct Migration V9: migrate_pages() extension ... Browse Code »

    Add direct migration support with fall back to swap.

    Direct migration support on top of the swap based page migration facility.

    This allows the direct migration of anonymous pages and the migration of file
    backed pages by dropping the associated buffers (requires writeout).

    Fall back to swap out if necessary.

    The patch is based on lots of patches from the hotplug project but the code
    was restructured, documented and simplified as much as possible.

    Note that an additional patch that defines the migrate_page() method for
    filesystems is necessary in order to avoid writeback for anonymous and file
    backed pages.

  • 5d337b919   [PATCH] swap: swap_lock replace list+device ... Browse Code »

    The idea of a swap_device_lock per device, and a swap_list_lock over them all,
    is appealing; but in practice almost every holder of swap_device_lock must
    already hold swap_list_lock, which defeats the purpose of the split.

    The only exceptions have been swap_duplicate, valid_swaphandles and an
    untrodden path in try_to_unuse (plus a few places added in this series).
    valid_swaphandles doesn't show up high in profiles, but swap_duplicate does
    demand attention. However, with the hold time in get_swap_pages so much
    reduced, I've not yet found a load and set of swap device priorities to show
    even swap_duplicate benefitting from the split. Certainly the split is mere
    overhead in the common case of a single swap device.

    So, replace swap_list_lock and swap_device_lock by spinlock_t swap_lock
    (generally we seem to prefer an _ in the name, and not hide in a macro).

    If someone can show a regression in swap_duplicate, then probably we should
    add a hashlock for the swap_map entries alone (shorts being anatomic), so as
    to help the case of the single swap device too.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
