I set the __GFP_COMP flag to __get_free_pages(),
but the result was same.

Did you pass the __GFP_COMP flag to __get_free_pages?

Hi, everyone

How can I allocate physically contiguous huge page in kernel module ?
The routine of _get_fee_pages() fails whenever there are much free
memory in system.

I found the procedures for set hugepages with sysctl or
/proc/sys/vm/nr_hugepages
but I've not found the api for allocate the huge page in kernel.

Thanks in advnace.

Best Regards,
J.Hwan Kim
