Jan,

Thanks for your answer.
I have checked and I have no tricks with mapping flags (mount ext4 options : rw,nosuid,nodev,noatime,errors=continue,data=ordered) I have added high mem verification on grow_dev_page function just after the page creation with find_or_create_page function.
PageHighMem() is not null.
So you think, it's a good idea to look into mm/page_alloc.c and verify gfp flags?

regards,

Clement
