Would that work on a filesystem that supports sparse files?

We're talking about the filesystem driver itself issuing the write.

The above is a discussion about whether the filesystem driver or the block device driver would issue the SCSI commands.

This would never happen from userspace.

Why would you need to overwrite blocks of a sparse file? Which blocks would you be overwriting?
