Yes, but it is the only way to make midishare "mainline". So that it

will always work with any vanilla distribution kernel (that has, of

course, enabled its build). 
The other option would be to implement all of midishare in user space.

Well, the kernel maintainers of course. And whoever is maintaining it

now (sorry, I don't who that might be). I don't see what is the problem.

Assuming the kernel module is merged in (that might not be easy, of

course) then it will have to be kept up to date with the mainline kernel

but that is good. And probably not that much work, after all the

midishare kernel module is not evolving, right?

They don't need to update the kernel. Why would they? The midishare

kernel module will keep working on the older kernels, right?

That would be a good first step.

The "kernel module problem" is still there. I do distribute my own

kernels (not that I like to do that :-) but some users use the normal

Fedora kernel. Then I would have to track the Fedora kernels and build

midishare modules for them as well. And right now Planet CCRMA does not

have any software that needs it (except maybe for Common Music but I

have been using portmidi for that - yuck...)
