Thanks a lot for your information! Of course, I volunteer to help with testing & qualified feed-back. I might even help with the implementation if you can tell me where to look for the (hopefully well defined ;-) place in the filesystem code where sectors become known not to contain relevant data anymore. But since I'm unfamiliar with kernel-filesystem programming, it might take longer answering my questions then somebody involved with XFS already would need to insert the blkdev_issue_discard() calls.
