Subject: [PATCH 0/5]: memcg: obj stock and slab stat caching cleanups
Date: Mon, 2 Mar 2026 14:50:13 -0500 [thread overview]
Message-ID: <20260302195305.620713-1-hannes@cmpxchg.org> (raw)
This is a follow-up to `[PATCH] memcg: fix slab accounting in
refill_obj_stock() trylock path`. The way the slab stat cache and the
objcg charge cache interact appears a bit too fragile. This series
factors those paths apart as much as practical.
Based on today's mm-new.
