Date: Fri, 22 May 2020 10:49:51 -0400
Message-ID: <20200522144959.434379-34-sashal@kernel.org> (raw)
In-Reply-To: <20200522144959.434379-1-sashal@kernel.org>

From: Liu Yibin <jiulong@linux.alibaba.com>

[ Upstream commit 6633a5aa8eb6bda70eb3a9837efd28a67ccc6e0a ]

Interrupt has been disabled in __schedule() with local_irq_disable()
and enabled in finish_task_switch->finish_lock_switch() with
local_irq_enabled(), So needn't to disable irq here.
