[RFC PATCH-for-9.0 v2 09/19] hw/block/xen_blkif: Align structs with QEMU


From: Philippe Mathieu-Daudé
Subject: [RFC PATCH-for-9.0 v2 09/19] hw/block/xen_blkif: Align structs with QEMU_ALIGNED() instead of #pragma
Date: Tue, 14 Nov 2023 15:38:05 +0100

Except imported source files, QEMU code base uses
the QEMU_ALIGNED() macro to align its structures.
