Ok, I will try this from now on.

OK, this is not very useful for many cases. Yes, I am using automated log on these patches, because I used to have 240 of them and writing manual logs for them would be fun. Moreover, in many cases, writing manual logs don't bring any value since I would have to repeat the same things all over again: xyz conversions was found by using *.cocci pattern first, then looked at manually and it looked like a standard reference counter that frees the things after calling refcount_dec_and_test() (or its variation with lock which is rare). Other things also looked correct, like I didn't see increments from zero, counter starts at 1 etc. I would really have to repeat the same thing in each changelog. Does it really bring value?
