Yeah, and this series adds [kprobe(s)] and [ftrace] too.
I simply concern that the those module names implicitly become
special word (rule) and embedded in the code. If such module names
are not exposed to users, it is OK (but I hope to have some comments).
However, it is under /proc, which means users can notice it.

Thank you,
