You are correct about the scope of the changes, although many of them are already in the kernel. Chuck Lever just posted the mount changes and I have posted a second round of the NFS-RDMA patches. You can see these on [EMAIL PROTECTED] I would like to get them upstream in 2.6.23, but that's probably optimistic. > > > > As far as I can tell from the outside, the NFS/RDMA effort seems to > > have stalled -- whenever I talk to core NFS developers like Chuck > > Lever or Trond Myklebust, they say that they are just waiting for the > > NFS/RDMA developers to submit their changes for review.

I'm not sure when you talked to those guys, but as I mentioned, this is round-two of the patch submission. There is also a git tree that has these submitted patches available for download and testing. These are on a 2.6.22-rc6 base and the git URL is git://linux-nfs.org/~tomtucker/nfs-rdma-dev-2.6.git If you like, I can post the patchset here as well. > > > > Without visible progress towards getting NFS/RDMA into mergeable form > > soon, I think putting it into OFED 1.3 as anything other than a > > technology preview that may be dropped from future releases would be a > > very risky think to do.

Both Trond and Neal reviewed the previous patchset and provided feedback that I addressed in the most recent patchset. That said, I'm sure there will be quite a bit more before it's mergeable. > > - R. > > _______________________________________________ > > general mailing list > > [email protected] > > http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general > > > > To unsubscribe, please visit > > http://openib.org/mailman/listinfo/openib-general > _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
