Subject: [PATCH v2 0/2] memcg_kmem hooks refactoring

Hi,

this is v2 of the memcg_kmem hooks refactoring (RFC/v1 link at the end).
This just rebases the refactoring patches 1 and 2 so they can start to
be exposed to -next and other work on can base on that.  I'm not
including the kmem_cache_charge() patch here until we have a more
finished user than my previous unfinished attempt.

Vlastimil

Changes in v2:
- rebase to v6.9-rc1
- add reviewed-by's to patches 1+2
- drop patches 3+4 (kmem_cache_charge() and usage in vfs)
- Link to v1: https://lore.kernel.org/r/20240301-slab-memcg-v1-0-359328a46596@suse.cz
