That doesn't seem to trigger any bug on upstream FreeBSD 10.1-BETA2,
even though the stat st_size for a disk/partition device is 0...
Turns out that cddl/compat/opensolaris/sys/stat.h defines a special
fstat64 that additionally calls DIOCGMEDIASIZE if it is a character
device. But on GNU/kFreeBSD we're calling the plain GNU libc fstat64.
