Several of > the #defines for the IIO tools came in for 4.7. Since this is a It would be better for the userspace tools to use the headers from the kernel source tree instead of those from the "previous" kernel-headers package. This will lead to a bootstraping issue if that's not the case. Or is there any reason why it's must use system installed headers ?
