Uhm, yes. :-)

Joachim, what Dan's alluding to is the fact that I added that call. :-)

The problem is it's not the exact semantics for what I want. I want FUA=20
down to the array. Among other things, you can have an array that has a=20
Battery-Backed-up-Unit and will write FUA'd writes to the BBU and just=20
pass non-FUA through to the disks. Waiting for after the call can't change=
=20
that behavior. :-(

Take care,

Bill
