My understanding is that the kprobe is part of the standard linux 2.6 source tree. I am not able to find any files related to the kprobe in ppc 32 bit architecture source tree , however, there are some related files for ppc 64 bit architecture source tree. directory. What am I missing? Many thanks in advance, Bizhan -------------- next part -------------- An HTML attachment was scrubbed...
