When setting a PID filter in debugfs, we unnecessarily reset the
statistics, although there is no reason to do so. This behavior was
merely introduced with commit 9f114a03c6 "tools/kvm_stat: add
interactive command 'r'", most likely to mimic the behavior of
the tracepoints provider in this respect. However, there are plenty
of differences between the two providers, so there is no reason not
to take advantage of the possibility to filter by PID without
resetting the statistics.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
