11 1. Concepts: Kprobes, and Return Probes
25 Concepts: Kprobes and Return Probes
36 There are currently two types of probes: kprobes, and kretprobes
37 (also called return probes). A kprobe can be inserted on virtually
43 one or more probes, and the exit function unregisters them. A
48 There are also ``register_/unregister_*probes()`` functions for batch
49 registration/unregistration of a group of ``*probes``. These functions

54 probes work and how jump optimization works. They explain certain
