44 a base. A Kprobe is registered as a ftrace handler when the function entry
339 The right implementation is selected by the ftrace handler, see
356 the ftrace handler is unregistered and the struct klp_ops is
415 Livepatch is based on the dynamic ftrace. In particular, functions
416 implementing ftrace or the livepatch ftrace handler could not be
432 the ftrace handler. This operation has to be reverted on return.
433 Fortunately, the generic ftrace code has the same problem and all
434 this is handled on the ftrace level.
