There are 3 main parts to dcache scaling. This one primarily adds new locks to take over dcache_lock, and some pre/post prep and streamlining patches. The second implements fine grained locking, and is rather trivial after part 1. The third implements rcu-walk. rcu-walk depends on the first part, because it relies on using d_lock to protect the state of the dentry (when converting from rcu-walk to refcounted walk). Without the fine grained locing, we'd need to use dcache_lock for that, which would be a step backwards to put into path walking again.
