Subject: [PATCH 4.18 054/158] selftests/bpf: fix a typo in map in map test
4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roman Gushchin <guro@...com>
[ Upstream commit 0069fb854364da79fd99236ea620affc8e1152d5 ]
Commit fbeb1603bf4e ("bpf: verifier: MOV64 don't mark dst reg unbounded")
revealed a typo in commit fb30d4b71214 ("bpf: Add tests for map-in-map"):
BPF_MOV64_REG(BPF_REG_0, 0) was used instead of
BPF_MOV64_IMM(BPF_REG_0, 0).
I've noticed the problem by running bpf kselftests.
