*shrug*
fs/namespace.c::mnt_init(). Right now it allocates 1 page for hash table (order = 0), you can easily raise that. You might want to try and change the order of checks in lookup_mnt() loop - depending on your setup it might speed the things up, but I doubt that it would be noticable win. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
