If you're going to be paranoid, shouldn't you do something here to
make
sure the value's hit the device?
I thought the whole point of paranoia is that its inexplicable.
Here's a delusional reply: I didn't see any point to it.
1) a wmb would add overhead
A wmb() doesn't guarantee the write has reached the device.
2) the hardware is supposed to be looking at the status flag,
anyway, and not misbehaving.
But you're paranoid, right? Can't trust that device! :-)
