btrfs-progs: Allow btrfs_read_dev_super() to read all 3 super for super_recover.
Btrfs-progs superblock checksum check is somewhat too restricted for super-recover, since current btrfs-progs will only read the 1st superblock and if you need super-recover the 1st superblock is possibly already damaged. The fix is introducing super_recover parameter for btrfs_read_dev_super() and callers to allow scan backup superblocks if needed. Signed-off-by: Qu Wenruo <> Signed-off-by: David Sterba <>
