[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.
