Hmm. That does make me want to merge it early, but at the same time I suspect it has gotten almost no testing on real hardware. So despite looking "obvious" and fixing one bug, I'm a bit nervous and I suspect that the prudent thing to do is still to take it early in the 2.3.36 merge window, and just mark it for stable.
Is anybody a big floppy user (on _real_ hardware, preferably with more than a couple machines) and could test it? I do feel kind of stupid for not taking it, but I don't have the hardware or the interest in really installing any in my current machines, and even if it looks fine and fixes some issue, I just don't feel safe enough without some more confirmation... As far as I know, the floppy oops thing has _only_ been seen on KVM (likely due to timing that just doesn't happen on real hardware), and while the KVM floppy emulation is probably fairly good, it also clearly isn't equivalent to hardware.
