Instead of having implementations of a hashtable all over the kernel, we can re-use the code. New changes since the RFC: - Addressed last comments about previous patches. - RCU support. - Simplified the case where the hashtable is allocated statically, which is the common case. - A lot more places converted to use the new hashtable.
