Re: [PATCH v1 1/4] nfs: Define NFS_RDMA_PORT

[Devesh Sharma <devesh.sharma-dY08KVG/lbpWk0Htik3J/w@public.gmane.org>]

Oh! apologies if I was not clear what I wanted to say. I was thinking
this change will avoid the step to write the nfsrdma port number into
/proc/fs/nfsd/portlist file after starting the nfs server. This is
step is a part of configuring nfs-rdma server. However, for tcp such
entries are present by default in this file.

-Regards
Devesh
