[Qemu-devel] [PATCH 27/27] block: Fix serial number assignment

[Kevin Wolf]

From: Luiz Capitulino <address@hidden>

We should use 'dinfo->serial' length, 'serial' is a pointer, so
the serial number length is currently limited to the pointer size.

This fixes https://bugs.launchpad.net/qemu/+bug/584143 and is also
valid for stable.
