[PATCH 2/9] cache-tree: extract subtree_pos()

From
Derrick Stolee via GitGitGadget <gitgitgadget@gmail.com>
Date
Jan 20, 2021, 16:53 UTC
Message-ID
<a6f2406a79512f517a1bc2700f806c546bbe9ed6.1611161639.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.839.git.1611161639.gitgitgadget@gmail.com>
From: Derrick Stolee <dstolee@microsoft.com>

This method will be helpful to use outside of cache-tree.c in a later feature. The implementation is subtle due to subtree_name_cmp() sorting by length and then lexicographically.
