Subject: [PATCH 0/5] support batched checking of the young flag for MGLRU
Date: Tue, 24 Feb 2026 09:56:03 +0800 [thread overview]
Message-ID: <cover.1771897150.git.baolin.wang@linux.alibaba.com> (raw)
This is a follow-up to the previous work [1], to support batched checking
of the young flag for MGLRU.
Similarly, batched checking of young flag for large folios can improve
performance during large-folio reclamation when MGLRU is enabled. I
observed noticeable performance improvements (see patch 5) on an Arm64
machine that supports contiguous PTEs. All mm-selftests are passed.
Patch 1,2: cleanup patches.
Patch 3: add a new generic batched PTE helper: test_and_clear_young_ptes().
Patch 4: support batched young flag checking for MGLRU.
Patch 5: implement the Arm64 arch-specific test_and_clear_young_ptes().

Baolin Wang (5):
mm: use inline helper functions instead of ugly macros
mm: rmap: add a ZONE_DEVICE folio warning in folio_referenced()
mm: add a batched helper to clear the young flag for large folios
mm: support batched checking of the young flag for MGLRU
arm64: mm: implement the architecture-specific
test_and_clear_young_ptes()
