From 2fbc62e2a13fc22b6ae4910e295a2c10fb790486 Mon Sep 17 00:00:00 2001
From: Zoltan Karcagi <zkr7432@gmail.com>
Date: Mon, 12 Aug 2019 13:27:16 -0400
Subject: [PATCH] Fix include order between config.h and stat.h
At least on Arch linux ARM, the definition of struct stat in stat.h depends
on __USE_FILE_OFFSET64. This symbol comes from config.h when defined,
therefore config.h must always be included before stat.h. Fix all
occurrences where the order is wrong by moving config.h to the top.
This fixes the client side error "Stale file handle" when mounting from
a server running Arch Linux ARM.
