Arg, my bad, I introduced this issue when I converted from f_flags

Hrm, I thought I had tested sufficiently, but obviously I did not :(
Here's the test tool.

While quickly looking, I think it only affects NFSv2, which I think
I indeed didn't test. I only run tests for 32 bit and 64-bit user
space and NFSv3. But yes, NFSv2 is an important test too. Not sure
if I will find time for that today.

I think the problem case to worry about would have been on a 32-bit
NFS server (think embedded/bookshelf NAS servers) and NFSv3, since
that's where the inconsistency would have meant that hash2pos would
use the 32-bit codepath, but pos2maj_hash would use the 64-bit
codepath, and so then...  kablooey.

Will send an updated version later on.

If it's just those changes, no worries, as I've already fixed up the
f_flags vs. f_mode issue in my copy of the patches.

Let me know if there are any other changes that you'd like to make or
issues that you've spotted.
