60 by using a compiler feature to insert a small, 5-byte No-Operation

75 It's first purpose is to trace the duration of functions and
142 to be scheduled in, starting from the point it has woken up.

284 The changes to the code are done by a kernel thread that
285 wakes up once a second and checks to see if any ftrace calls
287 and modifies the code to jump over the call to ftrace.

326 However, it should be safe to use on e.g. unused portion of VRAM.
