From 4614619ee4ad96d2715dc41f9430fb43335c15d2 Mon Sep 17 00:00:00 2001 From: John Snow Date: Sat, 4 Jul 2015 02:06:04 -0400 Subject: ahci: stash ncq command For migration and werror=stop/rerror=stop resume purposes, it will be convenient to have the command handy inside of ncq_tfs. Eventually, we'd like to avoid reading from the FIS entirely after the initial read, so this is a byte (hah!) sized step in that direction.
