From 99ba55ad696944b37d5557bc5b4816890854fdb9 Mon Sep 17 00:00:00 2001 From: Stefan Behrens Date: Mon, 19 Mar 2012 16:17:22 +0100 Subject: [PATCH] Btrfs: fix btrfs_ioctl_dev_info() crash on missing device When a filesystem is mounted with the degraded option, it is possible that some of the devices are not there. btrfs_ioctl_dev_info() crashs in this case because the device name is a NULL pointer. This ioctl was only used for scrub. Signed-off-by: Stefan Behrens --- Reading git-format-patch failed
