/* Note that VG_(stat) and VG_(fstat) write to a 'struct vg_stat*' and
not a 'struct vki_stat*' or a 'struct vki_stat64*'. 'struct
vg_stat*' is not the same as either of the vki_ versions. No
specific vki_stat{,64} kernel structure will work and is
consistently available on different architectures on Linux, so we
have to use this 'struct vg_stat' impedance-matching type
Also note that the fieldnames aren't prefixed with "st_". This is because
st_atime et al are macros in sys/stat.h on Darwin, and using those names
screws things up.
