This is the userspace part for the new copy-on-fork attribute added to
the get sys netlink command.

The new attribute indicates that the kernel copies DMA pages on fork,
hence fork support through madvise and MADV_DONTFORK is not needed.

Kernel series was merged:
https://lore.kernel.org/linux-rdma/20210418121025.66849-1-galpress@amazon.com/

Changelog -
v1->v2: https://lore.kernel.org/linux-rdma/20210428114231.96944-1-galpress@amazon.com/
* Rebase kernel headers
* Print attributes on the same line
* Simplify if statement

Thanks
