Wen Yang 87beb66918 selftests: introduce additional eventfd test coverage
Add several new test cases which assert corner cases on the eventfd
mechanism, for example, the supplied buffer is less than 8 bytes,
attempting to write a value that is too large, etc.

	./eventfd_test
	# Starting 9 tests from 1 test cases.
	#  RUN           global.eventfd_check_flag_rdwr ...
	#            OK  global.eventfd_check_flag_rdwr
	ok 1 global.eventfd_check_flag_rdwr
	#  RUN           global.eventfd_check_flag_cloexec ...
	#            OK  global.eventfd_check_flag_cloexec
	ok 2 global.eventfd_check_flag_cloexec
	#  RUN           global.eventfd_check_flag_nonblock ...
	#            OK  global.eventfd_check_flag_nonblock
	ok 3 global.eventfd_check_flag_nonblock
	#  RUN           global.eventfd_chek_flag_cloexec_and_nonblock ...
	#            OK  global.eventfd_chek_flag_cloexec_and_nonblock
	ok 4 global.eventfd_chek_flag_cloexec_and_nonblock
	#  RUN           global.eventfd_check_flag_semaphore ...
	#            OK  global.eventfd_check_flag_semaphore
	ok 5 global.eventfd_check_flag_semaphore
	#  RUN           global.eventfd_check_write ...
	#            OK  global.eventfd_check_write
	ok 6 global.eventfd_check_write
	#  RUN           global.eventfd_check_read ...
	#            OK  global.eventfd_check_read
	ok 7 global.eventfd_check_read
	#  RUN           global.eventfd_check_read_with_nonsemaphore ...
	#            OK  global.eventfd_check_read_with_nonsemaphore
	ok 8 global.eventfd_check_read_with_nonsemaphore
	#  RUN           global.eventfd_check_read_with_semaphore ...
	#            OK  global.eventfd_check_read_with_semaphore
	ok 9 global.eventfd_check_read_with_semaphore
	# PASSED: 9 / 9 tests passed.

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.
