Ah, OK, I see why this is per LUN. You want to be able not to ignore
FUA if the backing storage is a removable media, right?

I actually see the most sense in disabling FUA on devices with their
own power supply for logical units which backing file is not (on) a
removable device unless the removable device has some kind of lock
(like CD-ROM's door).
Either way, I now see the point of having this option per-LUN.
Actually fua = 1 means ignorance of that flag.
ignore_fua would be better name then I think. This also stands for
module parameter.
Or even “nofua”. The other solution would be to change the meaning
to the opposite (1 meaning that FUA is not ignored).
