RFC about Comedi on a patch that remove a lot fo code

[Alessio Igor Bogani]

Dear Comedi developers,

Sorry for my bad english.

I would be happy to receive your considerations about that patch:

http://marc.info/?l=linux-next&m=123792129500760&w=2

I know that some users use Comedi on dual kernel approach systems.
Obviously I don't have any against this but i think that Linux git
tree isn't the right place to support those software (RTAI, Xenomai,
RTLinux and others). Those projects already released patches against
Linux source code so it very easy for them add also patch for Comedi
drivers in the same tarball.

At the already listed 8 reasons  in that email I want added a ninth one:
9) Give more chance for interested developers to fix it against RT_PREEMPT
http://marc.info/?l=linux-rt-users&m=124049407712792&w=2

Thanks!

Ciao,
Alessio

I am siding with you, and agree all of the RT stuff should be deleted
from the in-kernel comedi code, as there is on in-kernel users of it.

Also, the recent Linux RT changes will not need any of these
driver-specific changes at all from what I can tell, so they are now
obsolete.

Frank, unless you have any major objections, I'd like to remove this
code.

thanks,

greg k-h

I'm okay with it.

Thanks, I've now dropped all of the rt code from the tree.
