Subject: [PATCH bpf-next 0/4] bpf: improve verifier state analysis
Several improvements to verifier state logic.
Patch 1 - trivial optimization
Patch 3 - significant optimization for stack state equivalence
Patch 4 - safety check for liveness and prep for future state merging
Alexei Starovoitov (4):
bpf: speed up stacksafe check
selftests/bpf: check insn processed in test_verifier
bpf: improve stacksafe state comparison
bpf: add self-check logic to liveness analysis
