Question on dht_filter_loc_subvol_key() function (in dht-helper.c)

Yaniv Kaul
I'm reading the function, and unsure what's going on there, perhaps I'm missing something:
name_len = strlen(loc->name) - keylen;
new_name = GF_MALLOC(name_len + 1, gf_common_mt_char);
snprintf(new_name, name_len + 1, "%s", loc->name);

How exactly is there enough space to snprintf loc->name into new_name?
Y.
