Subject: [PATCH v7 13/21] NFSD fill-in netloc4 structure
Date: Fri, 6 Sep 2019 19:36:03 -0400 [thread overview]
Message-ID: <20190906233611.4031-14-olga.kornievskaia@gmail.com> (raw)
In-Reply-To: <20190906233611.4031-1-olga.kornievskaia@gmail.com>
From: Olga Kornievskaia <kolga@netapp.com>
nfs.4 defines nfs42_netaddr structure that represents netloc4.
Populate needed fields from the sockaddr structure.
This will be used by flexfiles and 4.2 inter copy
