[PATCH] kprobes: fix unloading of self probed module
When a kprobes modules is written in such a way that probes are inserted on
itself, then unload of that moudle was not possible due to reference
couning on the same module.
The below patch makes a check and incrementes the module refcount only if
it is not a self probed module.
We need to allow modules to probe themself for kprobes performance
measurements
This patch has been tested on several x86_64, ppc64 and IA64 architectures.
