[ 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.
