I really like the idea of controlling kprobes through sysfs.
However, ...

do you really need a "magic" file for this ? I don't know how
well sysfs supports mkdir/rmdir (if at all), but they would
seem to provide a much more natural interface. (VFS allows
rmdir to remove non-empty directories, so you wouldn't have
to rm -r.)
I don't think you need probe installation and message setting
to be atomic, so you could just assign a unique default
message, e.g. the probe address.
