I don't disagree with any of the above, just want to point out that TRIM

That's shouldn't be a problem. David Woodhouse created a standard
block device interface that should be suitable both for ATA and SCSI:
int blkdev_issue_discard(struct block_device *bdev, sector_t sector,
unsigned nr_sects, bio_end_io_t end_io);

I know, just wanted to point out to the broader audience that it is not
just trim ;-)
