[PATCH bpf-next] selftests/bpf: fix ringbuf test fetching map FD
From: Andrii Nakryiko <andrii@kernel.org>

bpf
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [selftests] (test runners & infrastructure), kernel selftest framework, the rest · Maintainers:

Seems like 4d1b62986125 ("selftests/bpf: Convert few tests to light skeleton.")
and 704e2beba23c ("selftests/bpf: Test ringbuf mmap read-only and read-write
restrictions") were done independently on bpf and bpf-next trees and are in
conflict with each other, despite a clean merge. Fix fetching of ringbuf's
map_fd to use light skeleton properly.
Fixes: 704e2beba23c ("selftests/bpf: Test ringbuf mmap read-only and read-write restrictions")
Fixes: 4d1b62986125 ("selftests/bpf: Convert few tests to light skeleton.")
