类型参数名称
struct klp_func *func
139  如果WARN_ON(!patched)则返回
141  如果WARN_ON(!rnal )则返回
144  ops等于klp_find_ops(rnal )
145  如果WARN_ON(!ops)则返回
148  如果链表只有一项则
151  ftrace_loc等于Convert a function address into the appropriate ftrace location.* Usually this is just the address of the function, but on some architectures* it's more complicated so allow them to provide a custom behaviour.
153  如果WARN_ON(!ftrace_loc)则返回
156  WARN_ON(register_ftrace_function - unregister a function for profiling.*@ops - ops structure that holds the function to unregister* Unregister a function that was added to be called by ftrace profiling.)
157  WARN_ON(ftrace_set_filter_ip( & fops, ftrace_loc, 1, 0))
