Shouldn't it be rather `return !(vma->vm_flags & VM_SYNC);`? There is
no field named `flags` in `struct vm_area_struct`.

[PATCH v6 4/6] dax: check synchronous mapping is supported
This patch introduces 'daxdev_mapping_supported' helper
which checks if 'MAP_SYNC' is supported with filesystem
mapping. It also checks if corresponding dax_device is
synchronous. Virtio pmem device is asynchronous and
does not not support VM_SYNC.
