Dear Marius,

sorry, I searched, but I failed to spot PR 140797. I don't think that the
panic I'm seeing after my change has to do with the size parameter (if
it's incorrect though, please let me know). With the change I can read
files and do directory lookups just fine (tested with a 45 Gigabyte
file). I get the crash the minute I'm trying to write a file to the NFS
share.
