btrfs-progs: Add new option for specify chunk root bytenr
Add new btrfsck option, '--chunk-root', to specify chunk root bytenr. And allow open_ctree_fs_info() function accept chunk_root_bytenr to override the bytenr in superblock. This will be mainly used when chunk tree corruption. Signed-off-by: Lu Fengqi <> Signed-off-by: David Sterba <>
