Andrew raised the whole point about trace_mark() generating an

I'm not sure why this comes up again and again, but it's utter bullshit.
trace_mark does not generate any kind of user interface, just purely
a kernel internal interface.
trace_mark() is implement kvmtrace, which is propagated to userspace.
So while trace_mark() itself is not a userspace interface, one of its
users is.
It's an unstable interface. But so is dmesg; that's the nature of tracing.
