Subject: Accessing userspace created persistent eBPF maps from kernel bpf
 restricted C

Hello,
The samples and test cases have examples showing how user space
programs can pin maps and get pinned maps as FDs.  However, how would
one access a user-space created pinned map from kernel space, without
having to statically have a 'maps' section defined (and depend on the
elf loader)?

Thanks,
Kiran
