   How do you support

	   fsblkcnt_t    f_blocks  total number of blocks on file
				   system in units of f_frsize

   if you set statvfs.f_frsize = 0? I can image people use f_bsize to
   optimize I/O on the filesystem. f_frsize is mainly used for calculating
   filesytem usage.

Check if statvfs.f_frsize == 0, then use f_bsize instead.  This is
what the GNU fileutils do.
