Nothing uses it and nothing should use it, as tracing_off() and friends are better, as they disable the ring buffers related to tracing. The tracing_off_permanent() even disabled non tracing ring buffers. This is a bit drastic, and was added to handle NMIs doing outputs that could corrupt the ring buffer when only tracing used them. It is now obsolete and adds a little overhead, it should be removed. Signed-off-by: Steven Rostedt --- Reading git-diff-tree failed
