[dcmf] Lockless ROMIO driver

[Joseph Ratterman]

Rob,

I think these will be handled pretty quickly.  As I understand it, the 
problem is on two fronts:
The patch lacks an explicit copyright notice, so we don't know that it can 
be used.
We don't have the written guarantee that the patch was written by R Latham 
and therefore legal.
I certainly don't intend to imply that either of these are actually a 
problem, but it is important that we ensure that we follow the best 
practices.  IBM is especially concerned about these sorts of issues, and 
follow the rules from the beginning.

All that being said, our current changes are moving quite a bit faster 
than can be seen externally.  I just uploaded another tarball to the wiki, 
but that's not really a good way to do all this.  We are really hoping 
that a git server will be available soon.


Thanks,
Joe Ratterman

Hi Joe,

I agree that in general we must be careful that patches are provided 
under a consistent license. In the case of Argonne patches to this 
software, we are providing patches under the same license and 
copyright under which the code was originally written. Can we fast- 
track these?

Thanks,

Rob
