Hi Volker,

I'm not very familiar with the linux kernel lease/oplock API, but  
based on the comments in your commit message this patch looks fine.   
Out of curiosity, are you working on making level2 kernel oplocks work  
using samba on linux?  Have there been any recent improvements in the  
linux API that will make this easier?

It would definitely be cool to get RAW-OPLOCK passing against kernel  
oplocks on linux.  I have an smbtorture patch that gets RAW-OPLOCK  
passing against our kernel oplocks, but it's not quite ready to  
upstream yet.  My patch handles a few small differences in how we  
handle oplock breaks when compared with windows.
