[PATCH bpf-next v7 07/34] bpf: memcg-based memory accounting for bpf maps

[Roman Gushchin]

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.
