One of the proposals in this thread (that has got buried somewhere) was to expand any discard request sent down from the filesystem to encompass all the adjacent free space. I've checked with our SSD people and they're fine with this idea. dwmw2 says "it isn't actually that hard in FAT" and then interjects some personal opinion about this solution ;-) Is it hard in XFS? btrfs? ext2?
