Subject: [Patch v2 0/2] mm/pageblock: improve readability of some pageblock handling
Date: Wed, 27 Aug 2025 02:11:19 +0000	[thread overview]
Message-ID: <20250827021121.13645-1-richard.weiyang@gmail.com> (raw)

During code reading, found two possible points to improve the readability of
pageblock handling.

Patch 1: isolate bit is standalone and there are dedicated helpers. Instead of
check the bit directly, we could use the helper to do it.

Patch 2: remove PB_migratetype_bits and PB_migrate_end to reduce magical
computation.

v1->v2:
    remove PB_migratetype_bits and PB_migrate_end

Wei Yang (2):
  mm/page_alloc: use xxx_pageblock_isolate() for better reading
  mm/pageblock-flags: remove PB_migratetype_bits/PB_migrate_end

 include/linux/pageblock-flags.h | 12 +++++-------
 mm/page_alloc.c                 | 11 +++++------
