It occurred to me that, if there's one thing vvfat ought to be good
at, it is creating disk images with qemu-img convert (a driver disk
in my case).
It turns out the use case is really broken. qemu-img doesn't
complete at all, the resulting images often do not pass fsck,
and it's impossible to create a 1.44 MB disk image. This
series fixes all of the small problems I found.
Coding standard in this file is such a pain that I hardly bothered
about it.
Paolo Bonzini (6):
vvfat: fix out of bounds array_get usage
vvfat: do not fail if the disk has spare sectors
vvfat: need to use first_sectors_number to distinguish fdd/hdd
vvfat: unify and correct computation of sector count
vvfat: do not hardcode sector counts in error message
vvfat: reorganize computation of disk geometry
