Subject: [PATCH v2 2/2] cpuhp: Set cpuhp target for boot cpu
Date: Thu, 26 May 2022 12:06:15 -0400 [thread overview]
Message-ID: <20220526160615.7976-3-pauld@redhat.com> (raw)
In-Reply-To: <20220526160615.7976-1-pauld@redhat.com>
Since the boot cpu does not go through the hotplug process it ends
up with state == CPUHP_ONLINE but target == CPUHP_OFFLINE.
Set the target to match in boot_cpu_hotplug_init().
