------------------------------------
Fixes included in this service pack:
------------------------------------
* June 29, 2021: A performance neutral patch which fixes a code path where 
  the vendor has modified the storage2020.yaml file and enabled "skip_init= 1". 
  (This is not permitted for publication but is used by vendors for internal 
  testing because it saves time in nightly regression tests.) The use of 
  skip_init had an unintended side effect on workloads that contained 
  attributes that enabled O_DIRECT on file I/O calls. The patch eliminates 
  the side effect where use of skip_init in combination with the use of 
  O_DIRECT caused the transfer sizes to not match the definitions of the 
  workloads.

* April 12, 2021: A performance-neutral patch is available to fix an unexpected
  benchmark termination at a certain load increment.

* March 4, 2022: Performance neutral enhancment that improves compatibility with
  upcoming tools for dynamic visualization and interactive custom workload
  creation.

* March 4, 2022: Added get_control and put_control sources to the kit. These 
  provide the socket based API for the visualization tool to interface.
