Sorry for the delay, network access was spotty over the past few days,
and what little I did have was just my phone.

Anyway, yes, this was intended for v6.13 anyway so no harm there.
Glad you're setup again on kernel.org.

Hooking up to linux-next is pretty easy, basically just send some
mail, but if I can offer a suggestion you might want to make your
linux-next branch a automatically generated "composite" branch so you
are better able to get both linux-stable and linux-next patches tested
via the normal linux-next mechanisms.  I'm sure you've seen this
already, but here is the approach I take with the LSM tree:
