Hi all,
 
       I want to know how to run hugetlbshmget03? Does it need some arguments?
For I have run it several times, always got error "NOMEM" for cannot get hugetlb
page. But "cat /proc/meminfo" shows that free hugetlb pages are enough for its
request.
       Does anyone know how to handle this problem?
Hi Shenghui,

Have you run this testcase after setting up nr_hugepages ? You need to set the pages accordingly and then you need to run the testcase.

e.g:

echo 10 > /proc/sys/vm/nr_hugepages

Please post your result if you still finding issue.

Thanks
Rishi
