[PATCH -next v2 0/4] mm: per-node proactive reclaim

[Davidlohr Bueso <dave@stgolabs.net>]

Hello,

This is a tardy follow up to v1:
https://lore.kernel.org/linux-mm/20240904162740.1043168-1-dave@stgolabs.net/

Changes:
 - Not a change perse, but further discussed with mhocko potential usecases
   to justify upstreaming this interface. Nowadays NUMA represents the common
   abstraction for memory tiering representing devices of various performance
   characteristics. This interface makes a lot of sense given memcg's lack
   of NUMA awareness.
   
 - Consolidate both memcg and per-node flavors into a common helper. (Yosry)

Patch 1 is a small fixlet independent of the rest of the series.
Patches 2-3 make some of the machinery more generic.
Patch 4 adds the sysfs interface (which has further been deemed ok albeit
not following the one value per file "rule").

Please consider for v6.16.

Thanks!

  mm/memcg: make memory.reclaim interface generic
