718dc743c8 Enable particular ioclass eviction 
If partition's occupancy limit is reached, cachelines should be evicted from
 request's target partition.

Information whether particular partition eviction should be triggered is
carried as a flag by request which triggered eviction.

9bcafb5bfb seq_cutoff: Initialize each stream with different LBA 
Initializing each stream with unique LBA ensures there are no initial
rbtree collisions, and thus helps to avoid clustering of all the streams
into one big linked list instead of forming performance friendly proper
tree structure.
