[PATCH] kprobes: NULL out non-relevant fields in struct kretprobe
In cases where a struct kretprobe's *_handler fields are non-NULL, it is
possible to cause a system crash, due to the possibility of calls ending up
in zombie functions. Documentation clearly states that unused *_handlers
should be set to NULL, but kprobe users sometimes fail to do so.
Fix it by setting the non-relevant fields of the struct kretprobe to NULL.
