Subject: [PATCH RESEND 0/8] More stuff to charge to kmemcg
[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.
