Subject: [PATCH v2 4/4] arm64: Use test_tsk_thread_flag() for checking TIF_SINGLESTEP
Date: Thu, 2 Jul 2020 22:26:18 +0100 [thread overview]
Message-ID: <20200702212618.17800-5-will@kernel.org> (raw)
In-Reply-To: <20200702212618.17800-1-will@kernel.org>
Rather than open-code test_tsk_thread_flag() at each callsite, simply
replace the couple of offenders with calls to test_tsk_thread_flag()
directly.
