gpfs 3.5 and Samba Compatibility

[Nimrod Sapir]

You are right, of course. Also, I can't really think of a possible 
solution from the GPFS side that will solve the problem while keeping 
backward-compatibility. Is gpfs 3.5 compatibility included in the Samba 
roadmap? for which version? Is there anyone in the community (beside our 
team) which already started to examine this configuration? 

Thanks!
