Re: [PATCH v4 00/16] NFS/RDMA client side for Linux 4.3

[Anna Schumaker <Anna.Schumaker@netapp.com>]

Hi Chuck,

I've applied these patches locally without a problem (and I made sure to remove the pr_warns() in the last patch).  Are you planning to submit a v5, or are these ready for me now?

Thanks,
Anna
