Btrfs-progs: fix wrong arg sb_bytenr for btrfs_scan_fs_devices()
For most time, In open_ctree_*(), we use the first superblock (BTRFS_SUPER_INFO_OFFSET). However, for btrfs-convert, we don't, we should pass the correct sb_bytenr to btrfs_scan_fs_devices() rather than always use BTRFS_SUPER_INFO_OFFSET.This patch fix the following regression: mkfs.ext2 <dev> btrfs-convert <dev> warning, device 1 is missing Check tree block failed, want=2670592, have=0 read block failed check_tree_block Couldn't read chunk root Segmentation fault (core dumped) Signed-off-by: Wang Shilong <> Signed-off-by: David Sterba <> Signed-off-by: Chris Mason <>
