Subject: [PATCH 08/23] nfs: stash nfs_subversion reference into nfs_mount_info
Date: Thu, 23 May 2019 17:17:02 +0100 [thread overview]
Message-ID: <155862822265.26654.2410384551874971260.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <155862813755.26654.563679411147031501.stgit@warthog.procyon.org.uk>
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.
