openafs-modules-dkms 1.6.7-1ubuntu1: openafs kernel module failed to build

[a]

tried to get rid of #1433411 by updating Xubuntu 14.04.2 from utopic to vivid kernel which seems to bear the same problem
expected to install openafs
received error message instead

UpgradeStatus: No upgrade log present (probably fresh install)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I'm getting the same build errors on 14.04 systems with the vivid HWE. Coupled with lp:1433411, this makes impossible running OpenAFS on machines which require post-3.2 kernels.

(I meant post-3.13 kernels in the previous comment, sorry)

[Wolfram Schmidt (astrowolf1974)]

Also getting this build error with 14.04.3 LTS/3.19.0-30-generic.

[Kevin Adler (zeke-t)]

As a workaround, I use the OpenAFS stable PPA: https://launchpad.net/~openafs/+archive/ubuntu/stable

Somehow the f_dentry problem persists even though it is now openafs-modules-dkms 1.6.7-1ubuntu1.
