Ok, I understand. Thank for the explanation.

I have had a problem building the debian xenomai package till I have realised 
that I didn't have the correct patch, so I have investigated and I have found 
that you, in general, keeps the patch for the last kernel.

"Maybe", 
keep the patch last two kernels wouldn't be too much afford. I have to addmitt 
that I was thinking in debian, because the xenomai debian package is shipped 
with a patch for a kernel version that it's not in debian. But, you knows, 
someone that use xenomai knows to download a vanilla kernel.
