Hi,
If the standard for lockd is described in
http://www.opengroup.org/onlinepubs/009629799/chap9.htm#tagcjh_10,
then the linux lockd breaks the standard in numerous parts, mainly

- the protocole structures aren't the same (because on linux the structure used
is file_lock)

- lockd doesn't responds with the right message type for granted locks (more
precisely it uses a GRANTED_MSG in cases it should use GRANTED).

I have no problem with breaking the standard per se, and I fully understand the
reasons behind that, however it seems to me that it should lead to
interoperability issues. Does it ? According to the nfs howto (but it is an old
one there isn't such issues. Does it means that other nfs implementation also
use the file_lock structure ?

Pat
