Subject: [Qemu-devel] [PATCH 07/16] ahci: ncq sector count correction
Date: Fri, 19 Jun 2015 21:50:38 -0400	[thread overview]
Message-ID: <1434765047-29333-8-git-send-email-jsnow@redhat.com> (raw)
In-Reply-To: <1434765047-29333-1-git-send-email-jsnow@redhat.com>

This value should not be size-corrected, 0 sectors does not imply
1 sector(s). This is just debug information, but it's misleading!
