Well if the underlying OS exports a 64-bit locking interface
then Samba expects it to actually work. If it's running over
a filesystem that doesn't support it then it's the kernel's
job to map the 64-bit requests to whatever the underlying
transport expects. So maybe it'd be more accurate to describe
it as a nfs client redirector bug :-).
