btrfs-progs: fix uninitialized copy of btrfs_fs_devices list
Noticed that at print_one_uuid() some of the members of btrfs_fs_devices contained some junk values. It took a while to dig this further, and found that we make a local copy of the btrfs_fs_devices list at search_umounted_fs_uuids() and wasn't initialized properly. Fixed using using calloc instead of malloc. Signed-off-by: Anand Jain <> [ switched to calloc ] Signed-off-by: David Sterba <>
