| H A D | fprobe.rst | 16 use fprobe. Compared with kprobes and kretprobes, fprobe gives faster
18 describes how to use fprobe.
20 The usage of fprobe
23 The fprobe is a wrapper of ftrace (+ kretprobe-like return callback) to
25 the `struct fprobe` and pass it to `register_fprobe()`.
27 Typically, `fprobe` data structure is initialized with the `entry_handler`
32 struct fprobe fp = {
37 To enable the fprobe, call one of register_fprobe(), register_fprobe_ips(), and
38 register_fprobe_syms(). These functions register the fprobe with different types
41 The register_fprobe() enables a fprobe by function-name filters.
