Subject: [PATCH 05/27] arm64: fpsimd: Simplify uses of {set, clear}_ti_thread_flag()
Date: Fri, 18 Aug 2017 17:36:27 +0100 [thread overview]
Message-ID: <87efs8lto4.fsf@linaro.org> (raw)
In-Reply-To: <1502280338-23002-6-git-send-email-Dave.Martin@arm.com>
Dave Martin <Dave.Martin@arm.com> writes:
> The existing FPSIMD context switch code contains a couple of
> instances of {set,clear}_ti_thread(task_thread_info(task)). Since
> there are thread flag manipulators that operate directly on
> task_struct, this verbosity isn't strictly needed.
>
> For consistency, this patch simplifies the affected calls. This
> should have no impact on behaviour.
