From 72aef7318f54f0ec8c84c2bf2bb8edc5702d7dd0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 12 Sep 2010 23:42:56 +0200 Subject: use qemu_blockalign consistently Use qemu_blockalign for all allocations in the block layer. This allows increasing the required alignment, which is need to support O_DIRECT on devices with large block sizes.
