Subject: [PATCH 0/5] Clean up and fixes for swap
From: Kairui Song <kasong@...cent.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.
Kairui Song (5):
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: remove the swap lock in swap_cache_get_folio
swap: avoid ra statistic lost when swapin races
