The hugetlb filesystem type already supports set owner.
Please use that instead of an additional chown command.

If the user applications are going to request huge pages using mmap system
call, then it is required that system administrator mount a file system of
type hugetlbfs:
mount -t hugetlbfs \
-o uid=<value>,gid=<value>,mode=<value>,pagesize=<value>,size=<value>,\
min_size=<value>,nr_inodes=<value> none /mnt/huge
