Re: [PATCH[[2.5][3-11] update dvb subsystem core

[Michael Hunold]

Hello Christoph,

> What the problem with 2.5, dvb and devfs? 

The main problem is that our development "dvb-kernel" CVS tree *should* 
compile under 2.4 aswell, because most of the dvb-users don't want to 
participate in kernel development in general, but only on the 
development of the dvb subsystem. So work is done on the "dvb-kernel" 
tree, which should be synced with the 2.5 kernel frequently.

So, regarding devfs, I introduced #ifdefs around the functions that have 
changed recently. That's not nice, I know. But in my eyes it's important 
to keep the CVS and the kernel version more in sync.

IIRC Gerd Knorr has the same problems with his driver packages 
(regarding the i2c subsystem mainly), but he has written some perl 
scripts to remove the #ifdef stuff before submitting his patches...

No, you spoke to Holger I think, who has maintained the dvb-core kernel 
submissions before me.

I understand. But delaying the dvb updates just because a few calls to 
the devfs subsystem (which are now separated by #ifdefs and can easily 
be found) is not a good option either, or is it?
