(diff | wc -l) I agree with that, but as the results show, there does'nt seems to be much difference impact the numbers in the tested field. > Also, I question testing -rc code in the first place, except for > regression purposes. I tested the -rc code in orther to be able to compare the patched kernels against theird own source. > How does that effort compare for porting ADEOS code?
