Revision deb521c44fa529b24cc78a64702757a683f82487 authored by Linus Torvalds on 19 October 2012, 20:37:57 UTC, committed by Linus Torvalds on 19 October 2012, 20:37:57 UTC
In commit 0b173bc4daa8 ("mm: kill vma flag VM_CAN_NONLINEAR") we
replaced the VM_CAN_NONLINEAR test with checking whether the mapping has
a '->remap_pages()' vm operation, but there is no guarantee that there
it even has a vm_ops pointer at all.
Add the appropriate test for NULL vm_ops.
