Only if you can identity a specific patch you want backported to 2.6.32.
It's not the responsibility of the long-term stable tree maintainer to go looking through potentially tens of thousands of commits to find the one that should be backported. And if the code has changed too much since .2.6.32, and requires detailed reworking before the patch can get integrated into 2.6.32, then a subsystem developer will have to do that work.

Not all distributions will participate in the maintenance stable tree. Red Hat for example is probably worried about people (specifically, Oracle) taking their kernel expertise "for free" and bidding it against them. So it doesn't surprise me that they aren't submitting patches to the stable tree. After all, they would like you to purchase a support contract if you want to get high quality, supported kernel. Why should they give that work away for free? After all, their salaried developers have to get paid somehow. Others will contribute work in the hopes that other people will also contribute fixes back, but of course nothing forces Red Hat to do this.
The thing that you have to understand that this is all a volunteer effort, and a few of your messages sound like you are expecting people to do the work for you. It doesn't work that way. If you ask nicely, maybe one of the XFS developers will help you. But please don't expect free support. That will just annoy people.
