Re: NFS v3 cached directory content out of sync

FYI: For the reference a quick summary of this issue:

Linux Kernels older than 2.6.30 (or at least in 2.6.26 which we're
using) have this bug which can be reproduced as follows:

 * have two hosts: host A and host B - both having the same NFS
directory mounted and being in the same subdirectory on that NFS

 * host A: mkdir testdir; touch -m --date "2009-08-25 11:35" testdir
 * host B: ls testdir
 * host A: touch testdir/aNewFile; touch -m --date "2009-08-25 11:35" testdir
 * host B: ls testdir
   * shows an empty directory - even though 'aNewFile' just got
created. This remains so for hours.

The commit-set ID which is probably related (as of now I couldn't test
the above on 2.6.30):
