Subject: [PATCH mm-unstable v1 0/2] Track pages allocated for struct
Date: Thu, 31 Oct 2024 22:45:49 +0000 [thread overview]
Message-ID: <20241031224551.1736113-1-kinseyho@google.com> (raw)
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.

mm: add generic system-wide page counters
mm, swap: add pages allocated for struct swap_cgroup to vmstat
