r282071:

Integrate tools/regression/mqueue into the FreeBSD test suite as
tests/sys/mqueue

r282074:

Integrate tools/regression/aio/aiotest and tools/regression/aio/kqueue into the
FreeBSD test suite as tests/sys/aio

r282133:

Fill in the copyright boilerplate for the test program

r282134:

Add initial (unpolished) macros for interfacing with the FreeBSD test suite

This is very rough, but will be replaced/redesigned some time soon after I fix
the Jenkins breakage I introduced

r282135:

Use ATF_REQUIRE_KERNEL_MODULE instead of aio_available function

r282136:

- Use ATF_REQUIRE_KERNEL_MDOULE to require aio(4)
- Don't use /tmp as a basis for temporary files as it's outside of the ATF
  sandbox
- Don't override MAX macro in sys/param.h

r282137:

Use PLAIN_REQUIRE_KERNEL_MODULE to require "mqueuefs"

r282138:

Adjust CFLAGS to find freebsd_test_suite/macros.h

- * Regression test to do some very basic AIO exercising on several types of
- * file descriptors.  Currently, the tests consist of initializing a fixed
- * size buffer with pseudo-random data, writing it to one fd using AIO, then
- * reading it from a second descriptor using AIO.  For some targets, the same
- * fd is used for write and read (i.e., file, md device), but for others the
- * operation is performed on a peer (pty, socket, fifo, etc).  A timeout is
- * initiated to detect undo blocking.  This test does not attempt to exercise
- * error cases or more subtle asynchronous behavior, just make sure that the
- * basic operations work on some basic object types.
