If a kernel module crashes, you panic the kernel (normally).

eBPF probes can't crash and are determanistically safe (they aren't actually Turing complete). So you are unlikely to heavily impact application performance.

If you write your kernel module in eBPF (by pre-compiling to native code) it can't crash either.
