While it's great that you're putting the effort into adding a fixes tag
to your commits, I'm not sure what a fixes tag has to do with inclusion
in a stable tree.

It's a great help when we look into queueing something up, but on it's
own it doesn't imply anything.

This mail is your two week warning that this patch might get queued to
stable, nothing was actually queued just yet.

I'm curious, how does this process work? Is it on a mailing list
somewhere?

I've added drivers/net/ethernet/mellanox/ to my blacklist for auto
selection. It's very easy to opt out, just ask... I've never argued with
anyone around this - the maintainers of any given subsystem know about
it way better than me.
