Leo Yan e6841818e2 perf tests bp_account: Fix leaked file descriptor
[ Upstream commit 4a6cdecaa1497f1fbbd1d5307a225b6ca5a62a90 ]

Since the commit e9846f5ead26 ("perf test: In forked mode add check that
fds aren't leaked"), the test "Breakpoint accounting" reports the error:

  # perf test -vvv "Breakpoint accounting"
  20: Breakpoint accounting:
  --- start ---
  test child forked, pid 373
  failed opening event 0
  failed opening event 0
  watchpoints count 4, breakpoints count 6, has_ioctl 1, share 0
  wp 0 created
  wp 1 created
  wp 2 created
  wp 3 created
  wp 0 modified to bp
  wp max created
  ---- end(0) ----
  Leak of file descriptor 7 that opened: 'anon_inode:[perf_event]'

A watchpoint's file descriptor was not properly released. This patch
fixes the leak.

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.
