Bug#886768: Acknowledgement (linux-headers-3.16.0-5-amd64: inode_change_ok() missing, breaks openafs module build)

[Arne Nordmark <nordmark@mech.kth.se>]

Newer OpenAFS versions replace

code = inode_change_ok(inode, &newattrs);

by

code = setattr_prepare(file_dentry(afile->filp), &newattrs);

The file_dentry() helper is not present in linux-headers-3.16.0-5
either, but

code = setattr_prepare(afile->filp->f_path.dentry, &newattrs);

at least seems to compile. Is this the correct replacement?
