Subject: [PATCH v4 08/26] nfs: stash nfs_subversion reference into nfs_mount_info
Date: Fri, 13 Sep 2019 08:17:30 -0400
Message-ID: <20190913121748.25391-9-smayhew@redhat.com> (raw)
In-Reply-To: <20190913121748.25391-1-smayhew@redhat.com>

From: Al Viro <viro@zeniv.linux.org.uk>

That will allow to get rid of passing those references around in
quite a few places.  Moreover, that will allow to merge xdev and
remote file_system_type.
