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.
