30 kretprobes (also called return probes).  A kprobe can be inserted
58 When a kprobe is registered, Kprobes makes a copy of the probed

66 kprobe struct and the saved registers.

226 If the kprobe can be optimized, Kprobes enqueues the kprobe to an
227 optimizing list, and kicks the kprobe-optimizer workqueue to optimize
241 of kprobe optimization supports only kernels with CONFIG_PREEMPT=n.(**)
249 When an optimized kprobe is unregistered, disabled, or blocked by
250 another kprobe, it will be unoptimized.  If this happens before
251 the optimization is complete, the kprobe is just dequeued from the

623 On a typical CPU in use in 2005, a kprobe hit takes 0.5 to 1.0
627 return-probe hit typically takes 50-75% longer than a kprobe hit.
