Subject: [PATCH] QEMU/KVM: set cpu_single_env before flushing work
Date: Fri, 30 May 2008 23:26:47 +0200 [thread overview]
Message-ID: <48407117.1090904@web.de> (raw)
As Jerone pointed out, current kvm_invoke_guest_debug may segfault. The
reason is lacking re-initialization of cpu_single_env before
flush_queued_work is called. Here is the fix.
