Subject: [PATCH v3 0/2] promote mapped executable folios after first usage for MGLRU
Date: Fri, 17 Jul 2026 18:05:32 +0800 [thread overview]
Message-ID: <cover.1784268206.git.baolin.wang@linux.alibaba.com> (raw)
Now MGLRU's protection of mapped executable file folios is less reliable.
Follow the classical LRU's logic, promoting mapped executable file folios
after their first usage to give executable code a better chance to stay in
memory and improve workload performance (See patch 2 for more details).
Changes from v2:
https://lore.kernel.org/all/cover.1784197559.git.baolin.wang@linux.alibaba.com/
- Add acked tag from David. Thanks.
- Rename the exec-file-folio helper and move it into vmscan.c (per David).
Changes from v1:

- Add a new patch to clean up vma flags as preparation.
- Add a new helper to check exec file folios (per Kaisui).
- Promote exec file folios in lru_gen_set_refs (Per Sashiko).
