SYNOPSIS
--------
[verse]
'perf test [<options>] [{list <test-name-fragment>|[<test-name-fragments>|<test-numbers>]}]'

DESCRIPTION
-----------
This command does assorted sanity tests, initially through linked routines but
also will look for a directory with more tests in the form of scripts.

To get a list of available tests use 'perf test list', specifying a test name
fragment will show all tests that have it.

To run just specific tests, inform test name fragments or the numbers obtained
from 'perf test list'.

OPTIONS
-------
-s::
--skip::
	Tests to skip (comma separated numeric list).

-v::
--verbose::
	Be more verbose.

-F::
--dont-fork::
	Do not fork child for each test, run all tests within single process.

<div class='commit-subject'>tracing: Fix hwlat kthread migration</div><div class='commit-msg'>The hwlat tracer creates a kernel thread at start of the tracer. It is
pinned to a single CPU and will move to the next CPU after each period of
running. If the user modifies the migration thread's affinity, it will not
change after that happens.

The original code created the thread at the first instance it was called,
but later was changed to destroy the thread after the tracer was finished,
and would not be created until the next instance of the tracer was
established. The code that initialized the affinity was only called on the
initial instantiation of the tracer. After that, it was not initialized, and
the previous affinity did not match the current newly created one, making
it appear that the user modified the thread's affinity when it did not, and
the thread failed to migrate again.
