The first cluster group descriptor is not stored at the start of the group but at an offset from the start. We need to take this into account while doing fstrim on the first cluster group. Otherwise we will wrongly start fstrim a few blocks after the desired start block and the range can cross over into the next cluster group and zero out the group descriptor there. This can cause filesytem corruption that cannot be fixed by fsck.
