[PATCH mm-unstable v1 0/2] Track pages allocated for struct

[Kinsey Ho]

We noticed high overhead for pages allocated for struct swap_cgroup in
our fleet. This patchset adds the number of pages allocated for struct
swap_cgroup to vmstat. This can be a useful metric for identifying
unneeded overhead on systems which configure swap.

Before adding the new stat, Patch 1 introduces a generic system-wide
counting interface.
