There is no reluctance to submit the NFS-RDMA code for review. There have been several upstream changes to the NFS server recently. We (NetApp and Tom Tucker at OGC) are working on a new patchset for NFS-RDMA that is compatible with these changes. We are testing the code now. We will post the patches for review when we finish updating them. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
