[PATCH] Fix taskstats size calculation (use the new genetlink utility functions)
The addition of the CSA patch pushed the size of struct taskstats to 256 bytes. This exposed a problem with prepare_reply(), we were not allocating space for the netlink and genetlink header. It worked earlier because alloc_skb() would align the skb to SMP_CACHE_BYTES, which added some additonal bytes.
