It seems to me that parallelizing, without substantial locking (->
serialization) or very clever design, is likely to *reduce* correlations
between block requests and thus *increase* seeking substantially
You just need enough threads. If there are 1000 threads, you'll have about 1000 requests in the device's queue at any time, and one of them is bound to be near where the head is now.
I don't know much about fsck; maybe the work can't be done with enough threads to do better than today's single thread.
