[PATCH bpf-next 02/35] 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 most map types for
large allocations.

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