Did this test include the followup patch mm-page_alloc-replace-local_lock-with-normal-spinlock-fix.patch?
From: Mel Gorman <mgorman@techsingularity.net> Subject: mm/page_alloc: replace local_lock with normal spinlock -fix Date: Mon, 27 Jun 2022 09:46:45 +0100
As noted by Yu Zhao, use pcp_spin_trylock_irqsave instead of pcpu_spin_trylock_irqsave. This is a fix to the mm-unstable patch mm-page_alloc-replace-local_lock-with-normal-spinlock.patch
