[PATCH v2 1/1] hotplug-cpu.c: show 'last online CPU' error in dlpar_cpu_offline()

[Daniel Axtens]

Hi Daniel,

Two small nitpicks:

> This patch adds a 'last online' check in dlpar_cpu_offline() to catch
> the 'last online CPU' offline error, eturning a more informative error
                                       ^--- s/eturning/returning/;


> +			/* device_offline() will return -EBUSY (via cpu_down())
> +			 * if there is only one CPU left. Check it here to fail
> +			 * earlier and with a more informative error message,
> +			 * while also retaining the cpu_add_remove_lock to be sure
> +			 * that no CPUs are being online/offlined during this
> +			 * check. */

Checkpatch has a small issue with this comment:

WARNING: Block comments use a trailing */ on a separate line
#50: FILE: arch/powerpc/platforms/pseries/hotplug-cpu.c:279:
+			 * check. */

Apart from that, this patch seems sane to me, but I haven't been able to
test it.

Kind regards,
Daniel
