Yes, I would first check if there's a section named "__verbose" as it
is right now. If yes, I would search the already setup module->kp for
the used parameter.

Proposals, not being sure how to implement that right now:

Default is to search e.g. for param "dprintk".

Provide a macro to override that default, e.g.

If the default or defined bool or other integer parameter is unequal
to 0 enable the p-flag on module load for all debug statements of this

Questions just in case the proposal is kind of ok:

Prepare the code to allow the setting of different future flags
unequal to 'p'?

Use a charp param instead of a bool to allow that?
