Well..  why?  Presumably this patch fixes some race.  A good
description of that race would be useful - partly because others may
then be able to suggest alternative ways of fixing that bug.

I'll merge these patches for some testing.

I did merge these patches three weekes ago:

fat-modify-nfs-mount-option.patch
fat-exportfs-rebuild-inode-if-ilookup-fails.patch
fat-exportfs-rebuild-inode-if-ilookup-fails-fix.patch
fat-exportfs-rebuild-directory-inode-if-fat_dget-fails.patch
documentation-update-nfs-option-in-filesystem-vfattxt.patch

But I have no record of Bruce or Ogawa having reviewed/acked them?
