Thanks.

 Rosebush is a hashtable, different from the rhashtable.  It is scalable
-(one spinlock per bucket), resizing in two dimensions (number and size
-of buckets), and concurrent (can be iterated under the RCU read lock).
-It is designed to minimise dependent cache misses, which can stall a
-modern CPU for thousands of instructions.
