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.
