[Impact]
autopkgtest caught a build failure with openafs-modules-dkms with the
xenial/linux kernel currently in -proposed (4.4.0-207.239).
Testing failed on:

error: implicit declaration of function ‘inode_change_ok’
[-Werror=implicit-function-declaration]

^
cc1: some warnings being treated as errors
This was caused by commit "fs: Give dentry to inode_change_ok()
instead of inode" applied to xenial/linux as part of the fixes for
CVE-2015-1350, which renamed inode_change_ok() to setattr_prepare().
[Fix]
The proposed fix is to cherry-pick commit
8aeb711eeaa5ddac5a74c354091e2d4f7ac0cd63 "Linux 4.9: inode_change_ok() becomes
setattr_prepare()" from openafs repository (git://git.openafs.org/openafs.git).
[Test]
Install openafs-modules-dkms on a xenial system running an older kernel
without the interface change (<4.4.0-207) and with a newer kernel with the
interface change (>=4.4.0-207). The openafs module should be built and loaded
with all kernels.
[Where problems could occur]
The fix is based on the detection made during build time of the function
available on the kernel headers. If the detection doesn't work correctly the
build would fail.
