I set the __GFP_COMP flag to __get_free_pages(), but the result was same.
Does this help? sourd/core/memalloc.c +170

Forgot to CC kernelnewbies: Did you pass the __GFP_COMP flag to __get_free_pages? On 8/9/12, J.Hwan Kim[off-list ref] wrote:quoted
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.
