Like the other patch, and as discussed before too, I don't think this
has any business being part of (virtual) hardware drivers, and instead
belongs in random.c, which might receive these notifications from a
variety of devices, and can thus synchronize things accordingly.
Please stop posting more of these same approaches. Same nack as the
other ones.
Note the intended usecase for this in userspace really has nothing to
do with RNGs. We just want an event that is generated when a machine
is duplicated so that we can request a new DHCP lease, and similar. I
don't see any relationship to random.c for that.


Checking up on this conversation. The intended use case has nothing to do with RNG - we merely need a notification for system level user space that a system clone operation happened so it can act on it.

Please consider taking the patch as is or advise on how to proceed to address this non-RNG use case.


Thanks,

Alex
