The number of incompatible kernel/module interface changes per kernel is most likely some medium three digit number. What you have in mind is therefore not really feasible. But we have several levels of kernels that incorporate future stuff, from -rc over -next to -mm, and you could implement automated runs of the systemtap testsuite against the latest ones. > - FChE cu Adrian -- "Is there not promise of rain?"
