[LTP] mkfs.vfat: Device partition expected, not making filesystem on entire device '/dev/vdb' (use -I to override)

[Petr Vorel]

Hi,

there is a problem with mkfs.vfat, when LTP_DEV is full block device:

# ltp_dev=/dev/vdb fsync04
...
fsync04.c:50: PASS: Test file synced to device
tst_test.c:1278: INFO: Testing on xfs
tst_mkfs.c:35 tst_mkfs_(): pev: fs_type: 'xfs'

tst_mkfs.c:103: BROK: mkfs.vfat:1: tst_test.c failed with 830

Do we want to add permanently -I to vfat?
Or is it too hacky to trying to workaround tool's problem in the code?

Kind regards,
Petr
