Subject[PATCH] mm, hugetlbfs: include mm.h for vm_operations_struct
Date
The infiniband umem code causes a build failure in some configurations:

In file included from drivers/infiniband/core/umem_odp.c:41:0:
include/linux/hugetlb.h: In function 'vma_kernel_pagesize':
include/linux/hugetlb.h:262:32: error: dereferencing pointer to incomplete type 'const struct vm_operations_struct'

Including the header file that defines the structure is sufficient to
avoid this.

Fixes: ac9284a6b670 ("mm, hugetlbfs: introduce ->pagesize() to vm_operations_struct")
