Looks rather like I picked the wrong expression for marking
rtdm_task_sleep_until deprecated. I would prefer to go for this variant

Too fast? My i-Pipe patched Linux 2.4 kernel did simply not built ;-).

OK, __deprecated_call__ does not make trouble with 2.4.

Yeah, and my 2.4 kernel was lying around in the corner, slightly dusty, definitely not touched for several months. Hell, the amount of regressions one (specifically I) can produce due to all this config variants is amazing. We all have a very well defined job in this project, and particularly: - I do produce the original silly bugs. - You are in charge of adding regressions to your past fixes of my bugs - Dmitry is in charge of finding why our common code breaks. - Wolfgang is in charge of making all the involved fixes compile properly. - Gilles is in charge of making the result run on bugous and/or sluggish hardware. Ok, all in all, my situation is the best one. Good. What would be really nice is a playground for patches, some build system you could post a patch series and a set of .configs to and that will then simply try to generate various kernels and the xenomai userland for various archs automatically, reporting back any errors or warnings. Without going through SVN with the changes every time. Just a dream. Niklaus already built most of this infrastructure for us, only the automated patching part seems to be missing so far: http://ngiger.dyndns.org/buildbot/ We would also have to alleviate the burden of his server by providing some dedicated hardware to do that, though.
