+Subject: bpf: update jmp32 test cases to fix range bound deduction
+
+From: Daniel Borkmann <daniel@iogearbox.net>
+
+[ no upstream commit ]
+
+Since commit f2d67fec0b43 ("bpf: Undo incorrect __reg_bound_offset32 handling")
+has been backported to stable, we also need to update related test cases that
+started to (expectedly) fail on stable. Given the functionality has been reverted
+we need to move the result to REJECT.
