Global free cacheline list is divided into a set of freelists, one per execution context. When attempting to map addres to cache, first the freelist for current execution context is considered (fast path). If current execution context freelist is empty (fast path failure), mapping function attempts to get freelist from other execution context list (slow path). The purpose of this change is improve concurrency in freelist access. It is part of fine granularity metadata lock implementation. Signed-off-by: Adam Rutkowski <adam.j.rutkowski@intel.com>
