Exception: Failed to attach BPF program do_ret_sys_kill to kretprobe sys_kill

i using [adeb](https://github.com/joelagnel/adeb) running on android pixel4xl
kernel versiong 4.14 (4.14.170-g551313822-dirty_audio-g199e9bf)
bcc version latest

kernel config

CONFIG_BPF=y
CONFIG_BPF_JIT=y
CONFIG_HAVE_EBPF_JIT=y
CONFIG_KPROBE_EVENTS=y
CONFIG_UPROBE_EVENTS=y
CONFIG_BPF_EVENTS=y
CONFIG_DEBUG_PREEMPT=y
CONFIG_PREEMPTIRQ_EVENTS=y
CONFIG_FTRACE_SYSCALLS=y

I don't know what to do

Start with /usr/share/bcc/tools/killsnoop at the attach_kretprobe call and inspect bcc/__init__.py around attach_kretprobe. Reproduce the failure on the reported Android Pixel 4 XL kernel, then compare the kernel's kprobe and BPF support with the required sys_kill hook. Done means identifying the compatibility cause and recording a supported configuration or a reproducible fix.
