That's only for virtual disks, and that is not where the problem is (was). For most people this is not a solution. I have an almost-ready patch that implements linux_read() syscall. This will check if we are reading from a raw disk and in that case it will enlarge the read() to the next sector boundary. I have it working in the kernel but I have problems returning the right read buffer to userland.
