I # dropped the change that caused that bug and replaced it entirely with # something much more restrained. Unfortunately that required some # rebasing. # # Some successes after this set of changes: There are few enough calls # to do_exit to audit in a reasonable amount of time. The lifetime of # struct kthread now matches the lifetime of struct task, and the # pointer to struct kthread is no longer stored in set_child_tid. The # flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is # removed. Issues where task->exit_code was examined with # signal->group_exit_code should been examined were fixed. # # There are several loosely related changes included because I am # cleaning up and if I don't include them they will probably get lost. # # The original postings of these changes can be found at: # https://lkml.kernel.org/r/87a6ha4zsd.fsf@email.froward.int.ebiederm.org # https://lkml.kernel.org/r/87bl1kunjj.fsf@email.froward.int.ebiederm.org # https://lkml.kernel.org/r/87r19opkx1.fsf_-_@email.froward.int.ebiederm.org # # I trimmed back the last set of changes to only the obviously correct # once.
