If there are no enough stripes to handle, we'd better now always queue all
available work_structs. If one worker can only handle small or even none
stripes, it will impact request merge and create lock contention.
With this patch, the number of work_struct running will depend on pending
stripes

This is another attempt to create multiple threads to handle raid5 stripes.
This time I use workqueue.
raid5 handles request (especially write) in stripe unit. A stripe is page size
aligned/long and acrosses all disks. Writing to any disk sector, raid5 runs a
state machine for the corresponding

Neil,
This is another attempt to make raid5 stripe handling multi-threading.
Recent workqueue improvement for unbound workqueue looks very promising to the
raid5 usage. I had details in the first patch.
The patches are against your tree with patch 'raid5: make release_stripe
