There already _is_ a debugfs interface?
This must be new then.  I do not have debugfs no more, it is of no
use for me.  Sorry if i have missed anything.

There was a pool access ioctl that was removed.
Must i comment?  I have no problem with that, even though one
could say "i have a very good entropy generator" and wants to stir
the pool her/himself.  Direct I/O and even mapping of physical
pages in userspace is possible / discussed, so why that not?
Concurrent unlocked messing via binary ops surely improves the

Even the newest fairphone is only 70% fair iirc.  No.
Like the wonderful Zarah Leander sang in "Nur nicht aus Liebe
weinen" (badly: [anything, but] not crying due to love): the
answer is always renunciation.  (That was, granted, under the Nazi
regime.)  (And, it counteracts a bit with Hans Albers, "Hoppla!
Jetzt komm' ich", maybe.)
But now clear the streets, for me!
