Subject: [PATCH 03/10] watchdog/hardlockup: Don't use raw_cpu_ptr() in watchdog_hardlockup_kick()
Date: Fri, 26 May 2023 18:41:33 -0700 [thread overview]
Message-ID: <20230526184139.3.I660e103077dcc23bb29aaf2be09cb234e0495b2d@changeid> (raw)
In-Reply-To: <20230527014153.2793931-1-dianders@chromium.org>
In the patch ("watchdog/hardlockup: add a "cpu" param to
watchdog_hardlockup_check()") there was no reason to use
raw_cpu_ptr(). Using this_cpu_ptr() works fine.
