Subject: mm/compaction: set compact_cached_free_pfn correctly in update_pageblock_skip
Date: Thu, 3 Aug 2023 17:48:58 +0800
Patch series "Fixes and cleanups to compaction", v2.
This series contains random fixes and cleanups to free page isolation in
compaction. This is based on another compact series[1]. More details can
be found in respective patches.
This patch (of 4):
We will set skip to page block of block_start_pfn, it's more reasonable to
set compact_cached_free_pfn to page block before the block_start_pfn.
