From: Sam Bobroff Date: Thu, 30 Aug 2018 05:54:40 +0000 (+1000) Subject: spapr: Correct reference count on spapr-cpu-core X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ecda255ebab14adc35731fe67f8cfa70624010e2;p=qemu.git spapr: Correct reference count on spapr-cpu-core spapr_init_cpus() currently creates spapr-cpu-core objects via object_new() and setting their realized property to true. This leaves their reference count at two, because object_new() adds an initial reference and the realization attaches them to a default parent object which also increments the reference count. This causes a problem if one of these cores is hot unplugged: no delete event is generated for it because it's reference count doesn't reach zero when it is detached from it's parent. Correct this by adding a call to object_unref() in spapr_init_cpus().
