hugetlbfs not working

Hi,

I'm currently trying to get hugetlbfs working on the current git
version and am quite puzzled to see it not working. It appears as if
the ftruncate call fails:

open("/dev/hugetlbfs//kvm.vI3G8z", O_RDWR|O_CREAT|O_EXCL, 0600) = 7
unlink("/dev/hugetlbfs//kvm.vI3G8z") = 0
ftruncate(7, 157286400) = -1 EINVAL (Invalid argument)
dup(2) = 8
fcntl(8, F_GETFL) = 0x8001 (flags O_WRONLY|
O_LARGEFILE)
close(8) = 0
write(2, "ftruncate: Invalid argument\n", 28ftruncate: Invalid argument
) = 28
close(7) = 0

My host kernel is a 2.6.22.

Is this supposed to work? The first version did not have the ftruncate
call, so maybe it doesn't work at all with hugetlbfs?
