Subject: qemu: process: Don't needlesly clear the perf events in qemuDomainPerfRestart
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=22e464744d895539fceb35506e6065bb11c8f623;p=libvirt.git

qemu: process: Don't needlesly clear the perf events in qemuDomainPerfRestart

At that point the perf events struct should not be allocated so there's
no use in clearing it.
