[Qemu-devel] [RFC PATCH v1 1/4] qemu-log: Allow checking of the current mask

[Peter Crosthwaite]

Useful for heavy users of qemu_log_mask that want to avoid executing expensive
logic that sets up a qemu_log_mask when that mask is disabled. E.G.

if (qemu_log_get_mask() && LOG_GUEST_ERROR) {
        /* do my expensive logging data query */
}
qemu_log_mask(LOG_GUEST_ERROR, ...)
