Subject: [PATCH v2 08/26] nfs: stash nfs_subversion reference into nfs_mount_info
Date: Tue, 3 Sep 2019 16:31:57 -0400 [thread overview]
Message-ID: <20190903203215.9157-9-smayhew@redhat.com> (raw)
In-Reply-To: <20190903203215.9157-1-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.
