Yes it does. Old data in gpfs will just return all flags set to zero.
The vfs gpfs code then ensures that the self-relative bit is set on the
conversion to the windows flag format. From there on the behaviour is
identical to the previous which always just set the self-relative bit
when calling make_sec_desc.

Cheers,
