  allowing incompatible features above 0.0: (unknown version)
  features: lz4,new_siphash,inline_data,new_extent_overwrite,btree_ptr_v2,new_varint,journal_no_flush,alloc_v2,extents_across_btree_nodes

bcachefs (loop0): Version upgrade required:
Version upgrade from 0.32: (unknown version) to 1.7: mi_btree_bitmap incomplete
Doing incompatible version upgrade from 0.32: (unknown version) to 1.28: inode_has_case_insensitive
  running recovery passes: check_allocations,check_extents_to_backpointers,check_snapshots,check_subvols,check_inodes,check_dirents,set_fs_needs_rebalance
