[PROBLEM] Btrfs check original mode output is not that reader friendly already, it even includes pointer output: backref 15353727729664 parent 1140559929556992 not referenced back 0xc9133d70 tree backref 15353727729664 parent 14660022714368 not found in extent tree incorrect global backref count on 15353727729664 found 3 wanted 2 backpointer mismatch on [15353727729664 16384] In above case, the "0xc9133d70" is completely useless, as it's a pointer for the tree_backref structure. And the term "backref" is quite abused in above case. [ENHANCEMENT] To enhance the situation, let's use some output format from lowmem mode instead. Now above example will be changed to: tree extent[15353727729664, 16384] parent 1140559929556992 has no tree block found tree extent[15353727729664, 16384] parent 14660022714368 has no backref item in extent tree incorrect global backref count on 15353727729664 found 3 wanted 2 backpointer mismatch on [15353727729664 16384] And some example for data backrefs: data extent[12845056, 1048576] bytenr mimsmatch, extent item bytenr 12845056 file item bytenr 0 data extent[12845056, 1048576] referencer count mismatch (root 5 owner 257 offset 0) wanted 1 have 0 data extent[14233600, 12288] referencer count mismatch (parent 42139648) wanted 0 have 1 data extent[14233600, 12288] referencer count mismatch (root 5 owner 307 offset 0) wanted 0 have 1 data extent[14233600, 12288] referencer count mismatch (parent 30507008) wanted 0 have 1 Furthermore, the original function print_tree_backref_error() is a mess already, here we clean it up by exacting all the error output into a dedicated helper, print_backref_error(), so the function itself only need to find out errors.
