From: Mel Gorman ef1ff6b8c0 hugetlbfs: do not call user_shm_lock() for MAP_HUGETLB fix ... Commit 6bfde05bf5 ("hugetlbfs: allow the creation of files suitable for MAP_PRIVATE on the vfs internal mount") altered can_do_hugetlb_shm() to check if a file is being created for shared memory or mmap(). If this returns false, we then unconditionally call user_shm_lock() triggering a warning. This block should never be entered for MAP_HUGETLB. This patch partially reverts the problem and fixes the check.
