Hello Brad & Joseph,

I had a conversation with Tino Reichardt who wrote the TRIM parts of the 
patch.  Dave Kleikamp did not answer, maybe I choose the wrong e-mail adress 
or because he went from Big Blue to Oracle?

Tino will support me to get the patch upstream, but he is "a small light" (and 
I'm a nobody) on LKML, and he does not have the time for the all the e-mails 
that need to be written and answered; but I want to try to do that.  Do you 
have contact with the maintainers of the stable Linux versions (and give 
support)?

Can you provide a test environment for the stable Linux kernels when I send 
you git-patches against bare Linux 2.6.34, 2.6.35, 3.0, 3.2, 3.4, 3.5 and 3.6 
(i.e. a system with a SSD, maybe ssh access)? I can only reliably test my 
version 3.2.28, and to be honest I'm running JFS because it's rock-solid and 
do not want to gamble on my system... I could test in a virtual box, but 
that's probably not sufficient?

Up to now I do not use disk quotas, that's the part that needs testing besides 
usual stability tests.  Is there a test suite I shall use?

Thanx in advance,  =|o)

P.S. The patch is running on my system for weeks now very smooth and
stable :)
