* btrfs-progs: mkfs: remove unused code of format uuid stringZhao Lei2015-11-03

* btrfs-progs: mkfs: output device list in sorted orderZhao Lei2015-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | list_for_each_entry_reverse() in current code can not output devices in sorted order, because the sequence are broken in btrfs_alloc_chunk(). We can use list_sort() instead. Before patch: # mkfs.btrfs -f /dev/vdd /dev/vde /dev/vdf ... Number of devices: 3 Devices: ID SIZE PATH 3 2.60GiB /dev/vdf 1 2.60GiB /dev/vdd 2 2.60GiB /dev/vde After patch: # mkfs.btrfs -f /dev/vdd /dev/vde /dev/vdf ... Number of devices: 3 Devices: ID SIZE PATH 1 2.60GiB /dev/vdd 2 2.60GiB /dev/vde 3 2.60GiB /dev/vdf Signed-off-by: Zhao Lei <zhaolei@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>

| | | | | | | | | | | | | | | Btrfs has changed to delete subvolume/snapshot asynchronously, which means that after umount itself, if we've already deleted 'ext2_saved', rollback can still be completed. So this adds a check for ROOT_BACKREF before checking ROOT_ITEM since ROOT_BACKREF is immediately not in the btree after ioctl(BTRFS_IOC_SNAP_DESTROY) returns.
