Subject[PATCH v2 0/4] Clean up and fixes for swap
Date
From: Kairui Song <kasong@tencent.com>

This series cleanup some code path, saves a few cycles and reduce the
object size by a bit, also fixes some rare race issue of statistics.

Update from V1:
- Collect Huang, Ying's Reviewd-by.
- Use bloat-o-meter to show size change info in commit message as
suggested by Matthew Wilcox.
- Rework patch 4/4 as suggested by Huang, Ying.
- Drop a previouly invalid clean up patch.

Kairui Song (4):
swapfile: get rid of volatile and avoid redundant read
swap: avoid a redundant pte map if ra window is 1
swap: fold swap_ra_clamp_pfn into swap_ra_info
swap: avoid holding swap reference in swap_cache_get_folio
