We actually don't support module("NAME") for markers (which I realize
was in error in the text before too). We also support a format string,
so it can be either of these:
kernel.mark("MARK")
kernel.mark("MARK").format("FORMAT")
The current manpage is correct about these, if you want to look at
stapprobes.3stap.in.
Thanks,
