This is not something which has any justific= ation to be backported. Fixes: identifies the commit that introduced a bug for better reference, independently of whether the fix should be backported. If something shouldn't be selected by autosel one can add Cc: # reason to exclude from stable In this case I assume you said that because SW_SYNC is test infrastructure?= If so, AFAIK the stable team explicitly does backport test infrastructure as p= eople also run selftests on stable kernels.
