Jens Axboe 1181c1f923 [PATCH] noop-iosched: kill O(N) merge scan 
Profiling hit rates on merging shows that the last merge hint works
extremely well for most work loads.  So lets kill the linear merge scan in
noop-iosched, so it provides O(1) run time for any operation.

Testing credits go to Ken Chen from Intel.
