dentry->d_subdirs?
parent->dentry->...?

Or how about iterate_mounts() instead of loop over dentries?
For example (just a example),

struct args {
        /* input */
        struct dentry *root;

        /* output */
        struct vfsmount *mnt;
};

static int compare_mnt(struct vfsmount *mnt, void *arg)
{
        struct args *a = arg;

        if (mnt->mnt_root != a->root)
                return 0;
        a->mnt = mntget(mnt);
        return 1;
}

struct vfsmount *autofs4_find_vfsmount(struct dentry *root)
{
        int err;
        struct args args = {
                .root = root
        };

        err = iterate_mounts(compare_mnt, &args, current->nsproxy->mnt_ns);
}
