generic_file_aio_write on nfs

[Michal Simek]

Hi Benjamin,

I am doing LTP tests on Microblaze cpu and I am getting some faults.
I found that the problem is caused by generic_file_aio_write function.
I did quick patch with disable usage of generic_file_aio_write function and
use only write function which works. I haven't debug
generic_file_aio_write function.

I am running Linux with initramfs and LTP programs are run from nfs.

Have you ever met with this problem?

Thanks,
Michal
