[Qemu-devel] [PULL] monitor: eliminate monitor_event_state_lock

[Luiz Capitulino]

From: Paolo Bonzini <pbonzini@redhat.com>

This lock does not protect anything that the BQL does not already
protect.  Furthermore, with -nodefaults and no monitor, the mutex
is not initialized but monitor_protocol_event_queue is called
anyway, which causes a crash under mingw (and only works by luck.
under Linux or other POSIX OSes).
