Subject: [PATCH 0/4] fat: fix ESTALE errors

From: Namjae Jeon <namjae.jeon@...sung.com>

This patch-set eliminates the client side ESTALE errors when
a FAT partition exported over NFS has its dentries evicted 
from the cache.

One of the reasons for this error is lack of permanent inode 
numbers on FAT which makes it difficult to construct persistent 
file handles.This can be overcome by using the on-disk location
of the directory entries (i_pos) as the inode number.

Once the i_pos is available, it is only a matter of reading the
directory entries from the disk clusters to locate the matching
entry and rebuild the corresponding inode.

Namjae Jeon (4):
  fat: allocate persistent inode numbers
  fat (exportfs): rebuild inode if ilookup() fails
  fat (exportfs): rebuild directory-inode if fat_dget() fails
  Documentation: update nfs option in filesystem/vfat.txt
