SubjectRe: [PATCH AUTOSEL 4.9 03/11] selftests/resctrl: Change the default limited time to 120 seconds
From
Dear Stable Team,

I received the below notice about this commit being considered for
4.9 as well as other notices for it being considered for 4.14, 4.19,
5.4, 5.10, 5.15, 5.17, and 5.18.

I do not believe this commit is appropriate for stable because:
- It forms part of a series and without the other accompanying patches
from that series it does not do anything. Series is at:
https://lore.kernel.org/lkml/20220323081227.1603991-1-tan.shaopeng@jp.fujitsu.com/
- The original series was not not submitted for inclusion to stable and
none of its patches have a Fixes: tag.
- The series this patch forms part of aims to port resctrl_tests to the
kselftest framework and I do not believe such a change matches stable
criteria.
