Good day, The TODO document has the addresses of where to send a patch, but if you run get_maintainer.pl it gives me a different person to address it, gregkh for example. I have sent a patch to the persons on the TODO list, should I still copy to the maintainer in charge too? CC maybe? Another question, apart from the /drivers/staging and bugtracker, is there some where else to look for bug info? The mailing list? I just want to get the complete picture. Last question, I understand that if there is a bug, most of the time they tell you to try to reproduce it on the latest kernel. If it doesn't occur then everything is good and I should look for another one. But who is in charge of porting a bug fix like these to old kernels? How can I help? Or I, as a newbie, should focus more on the /drivers/staging and bugtracker? I want to thank in advance for your time and please let me know if I can read about all this in some website.
