Subject: page type is 3, passed migratetype is 1 (nr=512)
Date: Mon, 27 May 2024 01:58:25 -0700 [thread overview]
Message-ID: <ZlRLMcB80keLDL2o@infradead.org> (raw)
Hi all,
when running xfstests on nfs against a local server I see warnings like
the ones above, which appear to have been added in commit
e0932b6c1f94 (mm: page_alloc: consolidate free page accounting").
Here is a typical backtrace:
