With recent adoption of skc_cookie in struct sock_common, struct tcp_timewait_sock size increased from 192 to 200 bytes on 64bit arches. SLAB rounds then to 256 bytes. It is time to drop SLAB_HWCACHE_ALIGN constraint for twsk_slab. This saves about 12 MB of memory on typical configuration reaching 262144 timewait sockets, and has no noticeable impact on performance.
