30 * Regression test to do some very basic AIO exercising on several types of
31 * file descriptors. Currently, the tests consist of initializing a fixed
32 * size buffer with pseudo-random data, writing it to one fd using AIO, then
33 * reading it from a second descriptor using AIO. For some targets, the same
34 * fd is used for write and read (i.e., file, md device), but for others the
35 * operation is performed on a peer (pty, socket, fifo, etc). For each file
36 * descriptor type, several completion methods are tested. This test program
37 * does not attempt to exercise error cases or more subtle asynchronous
38 * behavior, just make sure that the basic operations work on some basic object
