ioctl_fat.2: Correctly reference volume ID instead of volume label
...
The description of FAT_IOCTL_GET_VOLUME_ID references volume name,
when it really should be volume ID since the volume label is
different in the FAT filesystem. This patch renames the incorrect
volume name references to volume id.
This man page supplies an example display_fat_volume_id.c program
that can be used to read the volume ID (serial number) from a
filesystem. Here is an additional test showing that the volume ID
and volume name are two different entities:
$ dd if=/dev/zero of=fat_volume bs=1M count=1
$ mkfs.fat -v -n MASNEYB fat_volume
[snip]
Volume ID is da8cecf2, volume label MASNEYB .
$ sudo mount -o loop fat_volume /mnt
$ ./display_fat_volume_id /mnt/
Volume ID da8c-ecf2
