sys_statvfs() is an abstraction layer over system-dependent statvfs()/statfs()
48
for particular POSIX systems. Due to controversy of what is considered more important
49
between LSB and FreeBSD/POSIX.1 (IEEE Std 1003.1-2001) we need to abstract the interface
50
so that particular OS would use its preffered interface.
