Subject: mm: introduce slabobj_ext to support slab object extensions
Date: Thu, 21 Mar 2024 09:36:28 -0700
Currently slab pages can store only vectors of obj_cgroup pointers in
page->memcg_data. Introduce slabobj_ext structure to allow more data to
be stored for each slab object. Wrap obj_cgroup into slabobj_ext to
support current functionality while allowing to extend slabobj_ext in the
future.
