The kernel reference counting is done at the module level, not the symbol level. Normally what happens is that when dvb_attach() is used to, it does a symbol_get() on the attach_XXX() function. At release time, the symbol_put() is done on at the release_XXX() function. Since both functions should be in the same module, it has the desired effect. If you're seeing the counter wrap around, dvb_attach() was probably not used in the first place, or the is an extra symbol_put() in there some place. _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
