Kuniyuki Iwashima e1bb28bf13 selftest: af_unix: Add test for SO_PEEK_OFF.
The test covers various cases to verify SO_PEEK_OFF behaviour
for all AF_UNIX socket types.

two_chunks_blocking and two_chunks_overlap_blocking reproduce
the issue mentioned in the previous patch.

Without the patch, the two tests fail:

  #  RUN           so_peek_off.stream.two_chunks_blocking ...
  # so_peek_off.c:121:two_chunks_blocking:Expected 'bbbb' == 'aaaabbbb'.
  # two_chunks_blocking: Test terminated by assertion
  #          FAIL  so_peek_off.stream.two_chunks_blocking
  not ok 3 so_peek_off.stream.two_chunks_blocking

  #  RUN           so_peek_off.stream.two_chunks_overlap_blocking ...
  # so_peek_off.c:159:two_chunks_overlap_blocking:Expected 'bbbb' == 'aaaabbbb'.
  # two_chunks_overlap_blocking: Test terminated by assertion
  #          FAIL  so_peek_off.stream.two_chunks_overlap_blocking
  not ok 5 so_peek_off.stream.two_chunks_overlap_blocking

With the patch, all tests pass:

  # PASSED: 15 / 15 tests passed.
  # Totals: pass:15 fail:0 xfail:0 xpass:0 skip:0 error:0

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 reStructuredText 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.
