[PATCH 0/2] btrfs: small improvement to leaf dump

[Qu Wenruo <wqu@suse.com>]

The first patch is just constify the tree dump infrastructure, exposed
during the development.

The second patch is the main dish, inspired by a report that turns out
to be bitflip in extent tree.
However the leaf dump in dmesg is pretty large (100+ slots), needs to
manually search the leaf using the bytenr from the error messages.

Thus if we can output the slot number, it would be much easier to locate
the problem, just like what we did in tree-checker.

  btrfs: print-tree: accept const extent buffer pointer
  btrfs: improve leaf dump and error handling
