Subject: [PATCH 1/2] nfsd4: common stateid-printing code
Date:   Mon, 11 May 2020 19:17:15 -0400
Message-Id: <1589239036-17100-1-git-send-email-bfields@redhat.com>
Sender: linux-nfs-owner@vger.kernel.org
Precedence: bulk

From: "J. Bruce Fields" <bfields@redhat.com>

There's a problem with how I'm formatting stateids.  Before I fix it,
I'd like to move the stateid formatting into a common helper.
