From bpftool's github repository issue [0]: When a Linux distribution has the kernel.kptr_restrict set to 2, bpftool prog dump jited returns "no instructions returned". This message can be puzzling to bpftool users who are not familiar with kernel BPF internals, so add a small hint for bpftool users to check the kernel.kptr_restrict setting similar to the DUMP_XLATED case. Outside of kernel.kptr_restrict, no instructions could also be returned in case the JIT was disabled.
