We were just checking for the 'err' variable, when we should really see
if there was some of the many checked errors that don't stop the test
right away.
Detected with clang 15.0.0:
44 75.23 fedora:37 : FAIL clang version 15.0.0 (Fedora 15.0.0-2.fc37)
tests/perf-record.c:68:16: error: variable 'errs' set but not used [-Werror,-Wunused-but-set-variable]
int err = -1, errs = 0, i, wakeups = 0;
^
1 error generated.
The patch introducing this 'perf test' entry had that check:
+ return (err < 0 || errs > 0) ? -1 : 0;
But at some point we lost that:
- return (err < 0 || errs > 0) ? -1 : 0;
+ if (err == -EACCES)
+ return TEST_SKIP;
+ if (err < 0)
+ return TEST_FAIL;
+ return TEST_OK
Put it back.
Fixes: 2cf88f4614c996e5 ("perf test: Use skip in PERF_RECORD_*")

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.
