Some LLDDs, like ipr, use nbytes and pad_len to determine the total data transfer length of a command. Make sure nbytes gets initialized for internally generated commands. Signed-off-by: Brian King <brking@xxxxxxxxxxxxxxxxxx> --- Jeff, This bug is already fixed in #upstream, with Tejun's patch, which does away with nsect, but it is still broken in 2.6.20. This is a resend of my original, 1 line patch. If this doesn't make 2.6.20, it might be a candidate for -stable, since without it, libata is not able to find SATA devices attached with ipr.
