I don't mean a literal trim command to the block device, but hints that get passed to the RAID layer to mark how blocks should be spread among the backing devices. I haven't put much thought into the details, but I suspect that there might not be so much information needed, so the RAID layer could be both generic and smart. It may not work out.
I'll probably be picking Allan's brain on a few things in the coming few months; amusingly, he mentioned doesn't use ZFS for ZFS development so that he can unload and reload the module, and he's interested in something that won't corrupt when he panics the kernel.
