Subject: [PATCH 2/7] rteval: Add idea of exclusive load module and make
|
||
|
|
stress-ng one
|
||
|
|
|
||
|
|
When running stress-ng as a load module in rteval, we don't want to run
|
||
|
|
kcompile or hackbench, so create the notion of an exclusive load module
|
||
|
|
and make stress-ng one.
|
||
