The original intention was to make the display of the printed content in
'__bch2_inode_unpacked_to_text ()' consistent, without considering other 
callbacks.

Or just modify it in the following way?
--- a/fs/bcachefs/inode.c
+++ b/fs/bcachefs/inode.c
@@ -534,6 +534,8 @@ int bch2_inode_v3_invalid(struct bch_fs *c, struct 
bkey_s_c k,
  static void __bch2_inode_unpacked_to_text(struct printbuf *out,
struct bch_inode_unpacked *inode)
  {
+       prt_newline(out);
+
         printbuf_indent_add(out, 2);
         prt_printf(out, "mode=%o", inode->bi_mode);
         prt_newline(out);


Thanks,
