/*
 * The size of this struct matters in full repo walk operations like
 * 'git clone' or 'git gc'. Consider using commit-slab to attach data
 * to a commit instead of adding new fields here.
 */
struct commit {
        struct object object;
        timestamp_t date;
        struct commit_list *parents;

        /*
         * If the commit is loaded from the commit-graph file, then this
         * member may be NULL. Only access it through repo_get_commit_tree()
         * or get_commit_tree_oid().
         */
        struct tree *maybe_tree;
        unsigned int index;
};

According to the instructions above, I wonder if you should use "commit_slab" to
store part of the data related to the commit object instead of
modifying the member
of struct commit itself?

See:
https://github.com/git/git/blob/master/commit-slab.h
https://github.com/git/git/blob/master/commit-slab-impl.h
https://github.com/git/git/blob/master/commit-slab-decl.h
https://lore.kernel.org/git/CAOLTT8Q8BEKCVwPDypW1w66P9_xP7QC0T-CnLqamqAL4haGzwA@mail.gmail.com/

Thanks.
