    Test Identification rt.os/aio/aio_cancel 2,3,5,6
    Problem Summary PG4R.00011 This request contends aio_cancel should be allowed to return AIO_ALLDONE in these tests.
    Problem Text


    The aio_cancel test cases 2, 3, 5 and 6 all make assumptions
    that the function under test will not complete between the time
    that aio_error validates that the aio_read or aio_write functions
    are in progress by returning EINPROGRESS. The formation of a "for"
    loop with the aio_error() function provides additional time for the
    function being tested to complete. The test cases should accept the
    result AIO_ALLDONE as implemenations can complete the processing
    prior to the aio_cancel() function is called.

    Review Recommendation No Resolution Given
    Review Response
    This request should be refused.

    Before issuing aio_cancel these tests establish conditions in which
    requests are outstanding for which completion is not physically possible:
    read requests against pipes/ptys/ttys which have no data available
    and write requests against pipes/ptys/ttys which are full and cannot
    accept any more data. Since these requests cannot complete, AIO_ALLDONE is
    a non-conforming return value from aio_cancel.

    We observe that these tests are all those in the set which have the
    aiocbp argument to aio_cancel set to NULL to indicate all requests
    should be cancelled, while those tests which establish the exact the same
    preconditions but set aiocbp to cancel specific requests apparently pass.
    If the situation was as the submitter contends these tests would
    perforce fail as well in the same way.

    As such we surmise that the implementation has a conformance problem
    in the aiocbp=NULL case, perhaps just returning the wrong value.
    Note that these tests allow AIO_NOTCANCELLED to be returned to accomodate
    the situation where the requests are in progress but some or all are in
    a non-cancellable state. Perhaps this is what the implementation
    means to return here.
