    Subject[PATCH 0/8] More stuff to charge to kmemcg
    Date
    Hi,

    This patch implements per kmemcg accounting of page tables (x86-only),
    pipe buffers, and unix socket buffers.

    Basically, this is v2 of my earlier attempt [1], addressing comments by
    Andrew, namely: lack of comments to non-standard _mapcount usage, extra
    overhead even when kmemcg is unused, wrong handling of stolen pipe
    buffer pages.

    Patches 1-3 are just cleanups that are not supposed to introduce any
    functional changes. Patches 4 and 5 move charge/uncharge to generic page
    allocator paths for the sake of accounting pipe and unix socket buffers.
    Patches 5-7 make x86 page tables, pipe buffers, and unix socket buffers
    accountable.

    Thanks,
