From b34e90429ce8a23546b6b927d4e151df4c113644 Mon Sep 17 00:00:00 2001 From: Richard Kennedy Date: Fri, 10 Sep 2010 12:19:43 +0100 Subject: libata: reorder ata_queued_cmd to remove alignment padding on 64 bit builds Reorder structure ata_queued_cmd to remove 8 bytes of alignment padding on 64 bit builds & therefore reduce the size of structure ata_port by 256 bytes. Overall this will have little impact, other than reducing the amount of memory that is cleared when allocating ata_ports.
