Subject: [PATCH 6/8] fs: move the fiemap definitions out of fs.h
Date:   Mon, 27 Apr 2020 11:58:56 +0200
Message-Id: <20200427095858.1440608-7-hch@lst.de>
In-Reply-To: <20200427095858.1440608-1-hch@lst.de>
References: <20200427095858.1440608-1-hch@lst.de>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-ext4-owner@vger.kernel.org
Precedence: bulk

No need to pull the fiemap definitions into almost every file in the
kernel build.
