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, 1572

If you don't truncate, how can you change the file size? hugetlbfs
doesn't support write().
I vaugely recall using ftruncate() o
