| D | fprobe.rst | 15 use fprobe. Compared with kprobes and kretprobes, fprobe gives faster
17 describes how to use fprobe.
19 The usage of fprobe
22 The fprobe is a wrapper of ftrace (+ kretprobe-like return callback) to
24 the `struct fprobe` and pass it to `register_fprobe()`.
26 Typically, `fprobe` data structure is initialized with the `entry_handler`
31 struct fprobe fp = {
36 To enable the fprobe, call one of register_fprobe(), register_fprobe_ips(), and
37 register_fprobe_syms(). These functions register the fprobe with different types
40 The register_fprobe() enables a fprobe by function-name filters.

259 bool "Kernel Function Probe (fprobe)"
266 This option enables kernel function probe (fprobe) based on ftrace.
267 The fprobe is similar to kprobes, but probes only for kernel function
