From d21e8776f6578be155714ae95c7d6c1bb03e8e34 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 24 Nov 2015 14:46:44 +0100 Subject: [PATCH] iothread: include id in thread name This makes it easier to find the desired thread. Use "IO" plus the id; even with the 14 character limit on the thread name, enough of the id should be readable (e.g. "IO iothreadNNN" with three characters for the number).
