Qi Zheng a6a1eb6214 bcache: dynamically allocate the md-bcache shrinker
In preparation for implementing lockless slab shrink, use new APIs to
dynamically allocate the md-bcache shrinker, so that it can be freed
asynchronously via RCU. Then it doesn't need to wait for RCU read-side
critical section when releasing the struct cache_set.
