>Description:
I run a custom kernel configuration and noticed that node_exporter would not work due to a crash in an lwp_park related syscall (see full stacktrace below)

As soon as anything tried to hit /metrics, it crashes.

I added COMPAT_90 to my kernel and that fixed it.

Here's the stack trace:
