Subject: [PATCH 0/3] x86/mm: DEBUG_PAGEALLOC musings
Date: Wed, 29 Jul 2026 13:08:07 +0200 [thread overview]
Message-ID: <20260729110807.797920433@infradead.org> (raw)
Hai,
my take on how we should be 'fixing' this DEBUG_PAGEALLOC thing. It appears to
boot in qemu with debug_pagealloc=on and such things.
