Subject: [RFC net-next 16/18] bpf: export function __bpf_map_get

From: Prashant Bhole <[email-masked]>

From: Jason Wang <[email-masked]>

__bpf_map_get is necessary to get verify whether an fd corresponds
to a bpf map, without adding a refcount on that map. After exporting
it can be used by a kernel module.
