I have found conflicting answers to this around the web, even a link to a launchpad bug: which is kind of left hanging.

So I'm curious, was TRIM support backported into the 2.6.32 kernel that is in 10.04? Does anyone know for sure?

Edit Although the above Launchpad Bug is relevant, it's this bug that is linked from the last comment on the above one that is most relevant:

In this, for Lucid update to stable release there is listed under: The following patches are in the stable release: * sata_mv: fix broken DSM/TRIM support (v2)

No; only critical bug fixes are added to stable releases, not new features. See StableReleaseUpdates. 10.04 is quite old now, so you should upgrade to 12.04 if you want to stay with an LTS release, or 12.10 if you don't.

I'm running 12.10 - this is for someone who has a business reason to run 10.04 (for now) for compatibility, but thanks for your answer. – Jayson Rowe Nov 30 '12 at 3:32
...and I do ask, do you know this for sure, because if I dig around Google again like I did the other night, I can find sources that say it was in fact backported into the 2.6.32 kernel. – Jayson Rowe Nov 30 '12 at 3:33
@JaysonRowe, actually it appears that the lucid kernel has ( and always did have ) discard support. – psusi Nov 30 '12 at 15:27
Thank you @psusi – Jayson Rowe Nov 30 '12 at 20:45
