From: Darrick J. Wong <djwong@xxxxxxxxxx>
Currently, this test relies on the XFS_IOC_FSCOUNTS ioctl to return
accurate free space information. It doesn't. Convert it to use statfs,
which uses the accurate versions of the percpu counters. Obviously,
this only becomes a problem when we convert the free rtx count to use
(sloppier) percpu counters instead of the (more precise and previously
buggy) ondisk superblock counts.
