commitda7f84cdf0upstream. Eaerlier, tracing was disabled when reading the trace file. This behavior was changed with: commit06e0a548ba("tracing: Do not disable tracing when reading the trace file"). This doesn't seem to work with the latency tracers. The above mentioned commit dit not only change the behavior but also added an option to emulate the old behavior. The idea with this patch is to enable this pause-on-trace option when the latency tracers are used.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
