Description
nfs only implements vfs_statfs and relies on the vfs_stdstatvfs wrapper to
provide a statvfs interface.
NFSv3 provides 64 bit values for free and available blocks, but the statfs
structure it fills uses only signed longs. As a result, these values get
cropped and later written back into a 64 bit integer in the statvfs struct,
leading to incorrect information.
nfs needs to implement both statfs and statvfs to fix this.

I'm currently testing an implementation of stavfs to fix this.
