Frank, All,

On 2017-12-20 09:32 -0500, Frank Hunleth spake thusly:
> The non-SMP scheduler was deprecated with the Erlang/OTP 20.0 release and
> slated for removal with the next major Erlang release. Since the non-SMP
> scheduler isn't even built anymore, this option no longer has the
> intended effect of saving space or compile time. The SMP scheduler
> supports both SMP and non-SMP processors, so removing the option will
> not break any platforms.
> 
> We do not need to add a legacy entry, because the new behavior is the
> same as with the option previously set (i.e. SMP enabled).
> 
> Signed-off-by: Frank Hunleth <fhunleth@troodon-software.com>

Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

Thanks! :-)

Regards,
Yann E. MORIN.
