Re: [PATCH 24/24] selftests/resctrl: Ignore failures from L2 CAT test with <= 2 bits

Hi Ilpo,

L2 CAT test with low number of bits tends to occasionally fail because of what seems random variation. The margin is quite small to begin with for <= 2 bits in CBM. At times, the result can even become negative. While it would be possible to allow negative values for those cases, it would be more confusing to user.

Ignore failures from the tests where <= 2 were used to avoid false negative results.

I think the core message is that 2 or fewer bits should not be used. Instead of running the test and ignoring the results the test should perhaps just not be run.
