Hi Jens,

I noticed that the contents of this branch are not in Linux-next.
Is this intentional?

I made a small last-minute change in the commit message for "optee:
register TEE devices only once fully initialized". That's why it may
seem new.

"tee: optee: ffa: support shared memory offsets on large-page kernels"
is brand new.

I thought it was better to send them sooner than to sit on them. Both
are added to my next branch, so I assume they will show on the next
update.

Please let me know if you want me to keep them on linux-next for a
minimum number of days before sending the pull request.

Thanks,
Jens

Thanks for the explanation, that makes sense. You need to decide how
confident you are in the contents before you send them, I was just
worried that this had not seen any testing at all because it was
inadvertently left out of linux-next.

If you are ever not sure, just mention that in the pull request message.
