This means the real timeout is now timeout * 2. This is not what
is supposed to happen. The hard watchdog timeout needs to happen at
'timeout'.
If you want to do this, it needs to be done using pre-timeout,
only the pre-timeout time (and thus the watchdog timeout written
into the chip) must be limited to timeout / 2. Pre-timeout must
by default be disabled and only be supported if an interrupt was
provided.
I don't see a need for an additional module parameter. Providing
an interrupt implies that pre-timeout support is wanted. This needs
to be documented accordingly.
I am not lot looking at the errors reported by 0-day. Please address those.
