    Subject[PATCH bpf-next v8 07/34] bpf: memcg-based memory accounting for bpf maps
    Date
    This patch enables memcg-based memory accounting for memory allocated
    by __bpf_map_area_alloc(), which is used by many types of bpf maps for
    large memory allocations.

    Following patches in the series will refine the accounting for
    some of the map types.
