Shuah Khan 41e583edb1 selftests: kvm: fix mismatched fclose() after popen()
[ Upstream commit c3867ab5924b7a9a0b4a117902a08669d8be7c21 ]

get_warnings_count() does fclose() using File * returned from popen().
Fix it to call pclose() as it should.

tools/testing/selftests/kvm/x86_64/mmio_warning_test
x86_64/mmio_warning_test.c: In function ‘get_warnings_count’:
x86_64/mmio_warning_test.c:87:9: warning: ‘fclose’ called on pointer returned from a mismatched allocation function [-Wmismatched-dealloc]
   87 |         fclose(f);
      |         ^~~~~~~~~
x86_64/mmio_warning_test.c:84:13: note: returned from ‘popen’
   84 |         f = popen("dmesg | grep \"WARNING:\" | wc -l", "r");
      |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

README

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.
