The bug as seen in the last patch below,
indicates that we need a mechanisum to tell when to use
the backup super_block. To do this it needs a frame-work,
and the patch #1 and #2 below provides the same without
change in the logic. The last patch uses the framework to
fix the bug.
v1->v2:
Accepts Eric and Zach review.
Seprates fix into 3 patches for easy logical understanding
Anand Jain (3):
btrfs-progs: Introduce flag BTRFS_SCAN_REGISTER to replace run_ioctl
btrfs-progs: Introduce flag BTRFS_SCAN_BACKUP_SB for
btrfs_read_dev_super
btrfs-progs: use BTRFS_SCAN_BACKUP_SB flag in btrfs_scan_one_device
