Replaying it after remove_migration_ptes(src, dst, 0) makes dst visible before it is requeued, so a concurrent rmap-removal path can mark dst partially mapped and trip the WARN in deferred_split_folio().</p> <p>Move the requeue before remove_migration_ptes() so dst is back on the deferred split queue before it becomes visible again.</p> <p>Because migration still holds dst locked at that point, teach deferred_split_scan() to requeue a folio when folio_trylock() fails. Otherwise a fully mapped underused folio can be dequeued by the shrinker and silently lost from split_queue.</p> <p>[ziy@nvidia.com: move the comment]</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>mm: fix deferred split queue races during migration</p> <p>migrate_folio_move() records the deferred split queue state from src and replays it on dst.
