From 29e05f202238fe0efee4a0ecccc3fd348448a37c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 6 Sep 2011 18:58:57 +0200 Subject: [PATCH] block: Reset buffer alignment on detach BlockDriverState member buffer_alignment is initially 512. The device model may set them, with bdrv_set_buffer_alignment(). If the device model gets detached (hot unplug), the device's alignment is left behind. Only okay because device hot unplug automatically destroys the BlockDriverState. But that's a questionable feature, best not to rely on it.
