Frank, All,
On 2017-12-18 12:04 -0500, Frank Hunleth spake thusly:
> The non-SMP scheduler is deprecated with the Erlang/OTP 20.0 release and
> slated for removal with the next major Erlang release. It also was hard
> to use in practice due to Erlang libraries calling APIs that were only
> available with the SMP scheduler. This change removes the non-SMP build
> option.

Removing an option usually involves adding it to the legacy:
Config.in.legacy
with some help for users to understand why the option was removed and
how to fix their configurations if needed.
In this case, however, I don;t think this is needed: a user that had
BR2_PACKAGE_ERLANG_SMP=y will still get it, because it is always built
unless requested not to.
Yet, this would warant a comment in the commit log.
Regards,
Yann E. MORIN.
