When we initial xfs_quota, we place lots of information into the
fs_table. This includes all the devices/mount points the user has
specified as a global command line parameter to report on, as well
as all the paths under project quota control.
There is a "current path" pointer (fs_path) maintained by the code
that points somewhere into the fs_table. After the table is
initialised, fs_path always points to the last entry in the table,
and hence has to be re-initialised to point at the desired entry
before it can be used properly.
fun code read :)

fs_table_lookup() can return NULL - especially the way I type.
