Merge branch 'rhashtable-bitlocks'
NeilBrown says:
====================
Convert rhashtable to use bitlocks
This series converts rhashtable to use a per-bucket bitlock
rather than a separate array of spinlocks.
This:
reduces memory usage
results in slightly fewer memory accesses
slightly improves parallelism
makes a configuration option unnecessary
The main change from previous version is to use a distinct type for
the pointer in the bucket which has a bit-lock in it. This
helped find two places where rht_ptr() was missed, one
in rhashtable_free_and_destroy() in print_ht in the test code.
