I will move the code for provider matching to frameworks, so it will be easy to add just dev_info after every failed attempt of getting resource, including deferring. This is the simplest solution and it should be similar in verbosity to deferred probing. Maybe other solution is to provide debug_fs (or device) attribute showing restrack status per device. > >> +int restrack_up(unsigned long type, const void *id, void *data) >> +int restrack_down(unsigned long type, const void *id, void *data) > Again I'm not sure that the up and down naming is meaningful in the > context of this interface. > >> +static void restrack_itb_cb(struct track_block *itb, void *data, bool on) >> +{ > itb_cb? Ups I forgot to rename few variables from my previous attempt. itb - stayed for interface tracker block.
