Hi Willy,

in [1] you say:

Can you share this "rebased to mainline" version of George's patch?
Maybe put your work "user-friendly-fetchable" in one of your
<kernel.org> Git tree (see [2])?

Yesterday random/random32/prandom mainline patches hit Linux
v5.8.1-rc1 (see [3]).

So, as I asked in my first email what is a suitable base?
Linux v5.9-rc1 (this Sunday) or if stable Linux v5.8.1 (next 1-2 days)

Thanks.

Regards,
