I think I kinda have XFS and AIO working now on 2.4.20pre8aa2, it is
failing on one test case, 5.t, which says that it does "- Write from a
mmap() of the same file. (5.t)".

All I have done so far is add the following 4 lines into
fs/xfs/linux/xfs_file.c:

        .kvec_read      = generic_file_kvec_read,
        .kvec_write     = generic_file_kvec_write,
        .aio_read       = generic_file_aio_read,
        .aio_write      = generic_file_aio_write,

In the file_operations struct after the fsync entry in there.

Anybody got any ideas why it would be failing on that specific test
case?
