Subject: [PATCH v2 0/5] mm, swap: misc cleanup and bugfix

A few cleanups and a bugfix that are either suitable after the swap
table phase I or found during code review.

Patch 1 is a bugfix and needs to be included in the stable branch,
the rest have no behavior change.

---
Changes in v2:
- Update commit message for patch 1, it's a sub-optimal fix and a better
  fix can be done later. [ Chris Li ]
- Fix a lock balance issue in patch 1. [ YoungJun Park ]
- Add a trivial cleanup patch to remove an unused argument,
  no behavior change.
- Update kernel doc.
- Fix minor issue with commit message [ Nhat Pham ]
- Link to v1: https://lore.kernel.org/r/20251007-swap-clean-after-swap-table-p1-v1-0-74860ef8ba74@tencent.com
