RE: [PATCH v1 00/13] NFS/RDMA patches for 3.17

["Steve Wise" <swise@opengridcomputing.com>]

Hey Chuck, 

I did some testing on this series.  Just 2 nodes, both nfs3 and nfs4 over cxgb4 and mlx4:

cthon b/g/s 10 iterations
iozone -a with direct IO and data validation
fio write and rand-rw testing of large IO/files and 8 threads.
xfs test suite.

No regressions seen.

Tested-by: Steve Wise <swise@opengridcomputing.com>
