sched, task_struct: stack_canary is not needed without CC_STACKPROTECTOR
The field stack_canary is only used with CC_STACKPROTECTOR. This patch reduces task_struct size without CC_STACKPROTECTOR. Signed-off-by: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com> LKML-Reference: <4A8A44CA.2020701@ct.jp.nec.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
