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 +++++------
