There's a bug on xfs cause statfs get negative f_ffree value from
a project quota directory. It's fixed by "de7243057 fs/xfs: fix
f_ffree value for statfs when project quota is set". So add statfs
testing on project quota block and inode count limit.
For testing foreign fs quota, change _qmount() function, turn on
project if quotaon support.

Hi,
There's one thing I don't understand, so CC ext4 mail list. Please
feel free to reply, if anyone knows that:
$ mkfs.ext4 $SCRATCH_DEV
$ tune2fs -O quota,project $SCRATCH_DEV
$ mount $SCRATCH_DEV $SCRATCH_MNT -o prjquota
$ quotaon -P $SCRATCH_MNT
$ mkdir $SCRATCH_MNT/t
$ xfs_quota -f -x -c "project -p $SCRATCH_MNT/t -s 42" $SCRATCH_MNT
$ xfs_quota -f -x -c "limit -p bsoft=100m answer" $SCRATCH_MNT
$ df -k $SCRATCH_MNT/t
Filesystem 1K-blocks Used Available Use% Mounted on
SCRATCH_DEV 102400 4 102396 1% SCRATCH_MNT
On XFS, the 'Used' field always shows '0'. But why ext4 always has
more 4k? Is it a bug or expected.
Thanks,
Zorro
