what was this comment referring to: /* intentionally ignoring frozen here */ After you move the cmci_rediscover() call, it is now in a place where we are no longer ignoring frozen (i.e. the old placement did the rediscover even if the CPU_TASKS_FROZEN bit was set - with the new placement we will skip rediscovery. So we were working around some interaction between cpu hotplug and frozen. Do we no longer need to do that? -Tony N�����r��y����b�X��ǧv�^�){.n�+����{����zX����ܨ}���Ơz�&j:+v�������zZ+��+zf���h���~����i���z��w���?�����&�)ߢf��^jǫy�m��@A�a��� 0��h���i
