4 Discovering Linux kernel subsystems used by a workload
14  * Understanding system resources necessary to build and run a workload
17    in use by a workload. The completeness of the system usage information
18    depends on the completeness of coverage of a workload.

32 the system resources in use by a workload. Once we discover and understand
33 the workload needs, we can focus on them to avoid regressions and use it
