As I am maintaining the Arch Linux package: There is no magic patch,
only the aforementioned patches are applied (gerrit 12264, 12265,
12268, 12274) and the kernel module compiles and works (as far as I can
tell) with Linux 4.5.4.

The first issue in the linked compile log is the following:
> /home/gsgatlin/redhat/sources/openafs-1.6.18/src/libafs/MODLOAD-4.5.5-201.fc23.x86_64-MP/osi_vnodeops.c: In function ‘afs_linux_follow_link’:

> Â Â Â Â Â nd_set_link(nd, name);

This particular error occurs if 0003-Linux-4.5-get_link-instead-of-
follow_link-put_link.patch (gerrit 12265) is not applied.

Cheers,
