[resending with all relevant lists in Cc] 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.
