Ah right. OK. ...looking at prepare-kernel.sh...it appears to skip updating the Xenomai version numbers if they are already present in init/Kconfig, though the Xenomai files appear to be copied anyway...
besides the i-pipe patches does Xenomai itself patch kernel files, besides Kconfig? looks pretty minimal if so. I wonder if it makes sense to allow kernel preparation of later Xenomai versions to a kernel source tree that's already been prepared...so there is a simpler upgrade path... in my experience applying i-pipe was the most risky aspect - I had to apply it to an already patched kernel and resolve some issues "by hand", and so is something that I *really* try and avoid doing, though I do want to stay current with Xenomai... I guess another approach is to keep a clean kernel patched with i-pipe but pre Xenomai....all gets messy....
