Re: [RFC PATCH v1 1/6] stash: mark `i_tree' in reset_tree() const

Hi Alban,

Thanks for working on this.

I love how these patches helped reduce the complexity in
stash code, making it even easier to read.

As reset_tree() does not change the value pointed by `i_tree', and that
it will be provided with `the_hash_algo->empty_tree' which is a
constant, it is changed to be a pointer to a constant.

Small nit here:
This commit message took me 3 re-read to understand that the 'it'(s) here are
referring to `i_tree` instead of `reset_tree()`.

Perhaps it would be better to rephrase it a little:

  In reset_tree(), the value pointed by `i_tree' is not modified. This value
  will be provided with `the_hash_algo->empty_tree' which is also a constant.

  Changed 'i_tree' to be a pointer to a constant.

Just a suggestion :-/
