There's a bug, the ustat() sysetm call is not implemented on someone
arch, but xfsprogs uses this to detect whether a filesystem is
mounted in platform_check_ismounted() function.
If ustat() is not implemented, platform_check_ismounted() return
"isn't mounted" if a filesystem is mounted, that's a big problem, it
will cause corruption.
