I wrote a test utility that tests different ways to flush NFS attribute
cache and data cache. Please test in your NFS setup and show me the
results, so I can make Dovecot v1.1 works well with NFS.
Run the test several times (3 should be enough) to make sure the output
stays the same, because the attribute cache flushes might incorrectly
say "OK". And of course attribute cache must not be disabled for this
test to work.
If you have other ideas how to flush either cache please tell me and
I'll update the test utility. I'd like to have a way to flush the cache
without having the NFS client send anything to server. Unfortunately all
of the below ways do that.
Results for Linux v2.6.15 and v2.6.18:
What's a good command to compile it? I have a Linux 2.6.20 NFS client
connected to a Linux 2.4.34 NFS client.
