After dvb-core has called mantis-fe->stop_feed(dvbdmxfeed) the last time (count to zero), no data should ever be copied with dvb_dmx_swfilter() by a tasklet: the target structure might be in an unusable state. Caller of mantis_fe->stop_feed() assumes that feeding is stopped after stop_feed() has been called, ie. dvb_dmx_swfilter() isn't running, and won't be called. There is a risk that dvb_dmx_swfilter() references freed resources (memory or spinlocks or ???) causing instabilities. Thus tasklet_disable(&mantis->tasklet) must be called inside of mantis-fe->stop_feed(dvbdmxfeed) when necessary.
