case NO.263 execute failure in xfstests-dev

[宋仁春]

Hi:

    When testing case 263 in xfstests, it always fails.
    It seems a bug of mmap in some case, and i do not know
    how to solve it. Can you help me?

    I get the error message as following:
    FSTYP -- xfs (non-debug)
    PLATFORM -- Linux/x86_64 RHEL6U2Beta-Intel64-150 2.6.32-202.el6.x86_64

    MOUNT_OPTIONS -- /dev/sda12 /sda12
