Series selftests/resctrl: Rework benchmark command handling | expand

Commit Message

Ilpo Järvinen Sept. 4, 2023, 9:53 a.m. UTC 
Benchmark command is initialized before resctrl FS check and
preparation code that can call ksft_exit_skip(). There is no strong
reason why the resctrl FS support check and unmounting it (if already
mounted), has to be done after the benchmark command initialization.

Move benchmark command initialization such that it is done not until
right before the tests commence. This simplifies rollback handling when
benchmark command initialization starts to use dynamic allocation (in a
change following this).
