Subject: [RFC PATCH 0/3] Improve the migration stats
Date: Wed,  3 Nov 2021 18:51:13 +0800	[thread overview]
Message-ID: <cover.1635936218.git.baolin.wang@linux.alibaba.com> (raw)

Hi,

According to talk with Zi Yan [1], this patch set changes the return
value of migrate_pages() to avoid returning a number which is larger
than the number of pages the users tried to migrate by move_pages() syscall.
Also fix the hugetlb migration stats and migration stats in
trace_mm_compaction_migratepages(). Please help to review. Thanks.
