[OpenAFS-devel] Openafs master kernel module does not build under Oracle Linux 3.8 unbreakable

[Karl Behler]

Dear All,

we try to build openafs 1.6.10 or alternatively openafs master on our 
Oracle Linux platform.
Linux lxaug27.aug.ipp.mpg.de 3.8.13-55.1.2.el6uek.x86_64 #2 SMP Thu Dec 
18 00:15:51 PST 2014 x86_64 x86_64 x86_64 GNU/Linux

We cloned the openafs master repository and started the build process 
for branch openafs-stable-1_6_x as well as for master.
But make fails with:

make[5]: Leaving directory `/usr/src/kernels/3.8.13-55.1.2.el6uek.x86_64'
FAILURE: make exit code 2

and in fact looking at osi_vnodeops.c:139 yields

code = generic_file_read_iter(iocb, iter);

while /usr/src/kernels/3.8.13-55.1.2.el6uek.x86_64/include/linux/fs.h 
contains

extern ssize_t generic_file_read_iter(struct kiocb *, struct iov_iter *,
                 loff_t);

However, there seem to be more incompatibilities as the messages say. So 
we stopped our analysis here.

Any idea what might be wrong with our kernel or our build trial?

Any advice appreciated.

Best regards,

Karl
