Why? cmd.flags specifies AT_WAIT, and as I remarked above it is indeed
waiting, so cmd, on the kernel stack, should outlive the I/O attempt.
OK, I now see that the *_exec_command()s in 5.2 do wait if AT_WAIT is set.
9.X does a ata_wait_cmd() for this.

ata_exec_command() will start the command, but, the completion of it
is usually signalled by an interrupt. Presumably, the 9.2 ATA-related code
takes care of this as ata_exec_command() takes a `xfer' parameter rather
than a bare command struct. How does 5.2 wait for ATA command completion?
