"I don't know what this buys us" == "no" AFAICT.

You might surprise me, but it looks like Linus wants more trusted
developers to come running to him going "LTT is really cool, we need
it for XXX".  Of *course* you think it's great, otherwise you wouldn't
work on it.

You misunderstand.  When Linus says "vendor-driven" he means what
usually happens is that vendors pick it up then the users come back
and convince Linus that it's worth including.

Hey, I feel your pain.  Really: the module rewrite has the same issue,
except I doubt a vendor would pick it up since it breaks compatibility
with standard userspace, and they have enough to worry about.

I've put your patch back in, but I expect Linus will say "Rusty you
fucking idiot, I already said "no" once."

Cheers,
Rusty.
