Subject: [PATCH] Ensure consistent struct stat definition
Date:   Thu, 31 Oct 2019 03:03:55 -0400
Message-Id: <20191031070355.26471-1-nazard@nazar.ca>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-nfs-owner@vger.kernel.org
Precedence: bulk

Although 2fbc62e2a13fc ("Fix include order between config.h and stat.h")
reorganized those files that were already including config.h, not all
files were including config.h.

Fixes at least stack smashing crashes in mountd on 32-bit systems.
