From: Ilya Dryomov Subject: [PATCH] Btrfs: set FMODE_EXCL in btrfs_device->mode Date: Tue, 15 Feb 2011 20:12:57 +0200 Message-ID: <20110215181257.GA9110@kwango.lan.net> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Cc: Chris Mason To: linux-btrfs@vger.kernel.org Return-path: List-ID: This fixes a bug introduced in d4d77629, where the device added online (and therefore initialized via btrfs_init_new_device()) would be left with the positive bdev->bd_holders after unmount. Since d4d77629 we no longer OR FMODE_EXCL explicitly on blkdev_put(), set it in btrfs_device->mode.
