This changelog is very poor for similar reasons as:
Re: [PATCH] perf/x86/intel/uncore: correct uncore num_counters
Please fix the changelog to conform to the standard changelog style:
- first describe the symptoms of the bug - how does a user notice?
- then describe how the code behaves today and how that is causing the bug
- and then only describe how it's fixed.
The first item is the most important one - while developers
(naturally) tend to concentrate on the least important point, the last
one.
Thanks,
Ingo
