> ext4_statfs_project() converts the selected space limit from bytes to
> filesystem blocks before checking whether it is nonzero. A nonzero quota
> smaller than one block therefore skips the project space adjustments.
>
> For example, a valid 1 KiB hard limit on a 4 KiB-block filesystem leaves
> statvfs() and df reporting the underlying filesystem's space, even when
> unprivileged data allocation fails with EDQUOT.
>
> Test the byte limit before converting it to filesystem blocks. The
> resulting zero block limit then clamps the project space statistics to
> zero. Keep the existing rounding and the rule that a zero byte limit
> means no quota.
