    [PATCH] kprobes: fix unloading of self probed module · df019b1d

    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.
