I placed the following in linux/fs/nfsd/export.c:

Then tried to export the root directory. This fails with EINVAL, yielding
the following from the log:

As you can see, something is getting scrambled with the dcache lookup. My
guess says that it's an endian problem (note the value for inode->i_dev is
the same as the nxp->ex_ino!).
Can you suggest a reasonable fix for this? I'd like to get the knfs
working on alpha.
