I have thought of adding "vers=3D<n>" ("nfsv4" would still work) to be more compatible with Solaris and Linux, but I've never gotten around to it. If no one else comes up with such a patch, I may get around to it someday, = rick > On Mon, Jun 2, 2014 at 3:23 PM, Rick Macklem <rmacklem@uoguelph.ca> > wrote: > > Hi, > > > > I think that the NFSv4.1 server code in projects/nfsv4.1-server is > > about ready to be merged into head. > > > > As such, if anyone has the resources to do so in the next 2 weeks, > > please take a look at the code and/or test it. > > > > Also, feel free to make any comments w.r.t. merging this code into > > head, such as preferred timing, whether or not you think it should > > happen, etc. > > > > If/when the merge is done, it will be fairly large, but shouldn't > > affect the NFSv3, NFSv4.0 server functionality (however, I may > > screw up and break them for a little while;-).
