[for-next][PATCH 13/13] tracing: Fix documentation about disabling options using trace_options

From: Steven Rostedt
Date: Wed May 08 2019 - 16:26:05 EST


From: "Srivatsa S. Bhat (VMware)" <srivatsa@xxxxxxxxxxxxx>

To disable a tracing option using the trace_options file, the option
name needs to be prefixed with 'no', and not suffixed, as the README
states. Fix it.
