From: Derrick Stolee via GitGitGadget Date: Wed, 20 Jan 2021 16:53:51 GMT Subject: [PATCH 1/9] cache-tree: clean up cache_tree_update() Message-ID: <0bccfd34ae5924aef0432fd6727debb75c052da5.1611161639.git.gitgitgadget@gmail.com> In-Reply-To: From: Derrick Stolee Make the method safer by allocating a cache_tree member for the given index_state if it is not already present. Also drop local variables that are used exactly once and can be found directly from the 'istate' parameter.
