While running the ftracetests, the pid filter test failed because the
instance "foo" existed, and it was using it to rerun the test under a
instance named foo. The collision caused the test to fail as the mkdir
failed as the name already existed.
As of commit b5b77be812 ("selftests: ftrace: Allow some tests to be run
in a tracing instance") all a selftest needs to do to be tested in an
instance is to set the "instance" flag. There's no reason a selftest needs
to create an instance to run its test in an instance directly.
Remove the open coded testing in an instance for the pid filter test and
have it set the "instance" flag instead.

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.
