Subject: cgroup: docs: add pswpin and pswpout items in cgroup v2 doc
Date: Tue, 18 Mar 2025 15:58:33 +0800

The commit 15ff4d409e1a ("mm/memcontrol: add per-memcg pgpgin/pswpin
counter") introduced the pswpin and pswpout items in the memory.stat of
cgroup v2.  Therefore, update them accordingly in the cgroup-v2
documentation.
