Except through the FDCS # macro, which just indexes a static allocation through teh current fdc, # which is always checked against N_FDC. # # Except the checking happens after we've already assigned the value. # # The floppy driver is a disgrace (a lot of it going back to my original # horrd "design"), and has no real maintainer. Nobody has the hardware, # and nobody really cares. But it still gets used in virtual environment # because it's one of those things that everybody supports. # # The whole thing should be re-written, or at least parts of it should be # seriously cleaned up. The 'current fdc' index, which is used by the # FDCS macro, and which is often shadowed by a local 'fdc' variable, is a # prime example of how not to write code. # # But because nobody has the hardware or the motivation, let's just fix up # the immediate problem with a nasty band-aid: test the fdc index before # actually assigning it to the static 'fdc' variable. # # Reported-by: Jordy
