Yes, I've created the MFC patches for stable 8 & 9 but we're just looking to close out an issue reported by Ajit Jain thread "seeing data corruption with zfs trim functionality" on freebsd-fs@ My current thinking is this is due to either a LSI FW issue, related to a know WS16 bug or potentially a merge problem, as Ajit wasn't using our code base directly. I posted the two main patch sets I'm looking to commit to that thread this morning, your welcome to test and let us know how you get on. If you are using LSI mps controllers, either ensure your using P16 FW or don't manually select Write Same delete methods for your disks to avoid the know FW bug which will cause corruption.
