[PATCH] pacct: avoidance to refer the last thread as a representation of the process
When pacct facility generate an 'ac_flag' field in accounting record, it refers a task_struct of the thread which died last in the process. But any other task_structs are ignored. Therefore, pacct facility drops ASU flag even if root-privilege operations are used by any other threads except the last one. In addition, AFORK flag is always set when the thread of group-leader didn't die last, although this process has called execve() after fork(). We have a same matter in ac_exitcode. The recorded ac_exitcode is an exit code of the last thread in the process. There is a possibility this exitcode is not the group leader's one.
