The following comment explains what linux_ustat should do:
/*
* lu.f_fname and lu.f_fpack are not used. They are always zeroed.
* lu.f_tinode and lu.f_tfree are set from the device's super block.
*/
linux_ustat fills in a structure with the above mention fields. The
meaning of f_tinode and f_tfree are explained by the following two
statements:
lu.f_tfree = stat->f_bfree;
lu.f_tinode = stat->f_ffree;
In short: given the (u)dev_t, get the FS statistics and return the
number of free blocks and inodes of the FS on that device.
