In-Reply-To: Your message of "Tue, 17 Feb 2004 10:49:26 CDT." <20040217154926.GI12142@localhost>
In message <20040217154926.GI12142@localhost> you write:
> CC'ed Rusty because this patch is applied on top of his cpuhotplug code.
Actually, the #ifdef around that function is wrong:
#if defined(CONFIG_NUMA) || defined(CONFIG_HOTPLUG_CPU)
/* If dest_cpu is allowed for this process, migrate us to it. */
void migrate_to_cpu(int dest_cpu)
We don't use this for HOTPLUG_CPU, but we call __migrate_task()
directly.
ie. #ifdef CONFIG_NUMA is sufficient.
I do think this is an obviously good idea though.
Rusty.
