I, Herton Ronaldo Krzesinski, apply for upload rights for linux-* packages.

Who I am

I'm Herton Ronaldo Krzesinski, I work for Canonical as a Kernel Developer (Generalist). I'm on Ubuntu Kernel team, currently working with stable kernels, helping taking care of updates and processes we use to release them. I also from time to time take a look at some bugs, working with reporters to diagnose and identify or make fixes (working on the stable kernels, currently I am mostly interested in proven regressions reported).

My Ubuntu story

My involvement

I started working with Ubuntu since I joined Canonical at February, 2011. In the beginning I was following and taking a look at several kernel bugs, either trying to fix issues or investigating problems reported by users (asking their help by asking more relevant information, helping on bisecting providing pre-built kernels, etc).

Now my efforts are concentrated mainly on kernel stable updates, helping kernel SRU updates, developing kernel team tools to keep up with the Kernel SRU workflow, etc.

Examples of my work / Things I'm proud of

Five examples of bugs reported which I helped triage/fix:
Oops after resume from hibernate on restore_image
mxb: general protection fault at v4l2_device_register_subdev+0x95
kvm_amd and qemu: BUG: unable to handle kernel NULL pointer dereference at 00000014
BUG: unable to handle kernel paging request at 00100104
2.6.38-10 panic after ejecting drive

Also I was responsible for working on several latest updates for kernel stable packages, which got signed/sponsored by other ubuntu kernel team members:

Areas of work

Until now, my work involved kernel bug handling and stable updates (only kernel related work).

All issues I had to deal involved mostly the kernel team until now. I communicate with colleagues inside the team depending on what's the matter, eg. for syncing linux-ec2 updates I check with Stefan Bader when necessary, for some arm related package pendency I seek first Paolo Pisatti. For kernel bugs related to current development distro release, I talk to the current kernel release manager when appropriate.

On kernel stable updates and tooling related to kernel SRU workflow, I work with Steve Conklin and Brad Figg.

Everything went ok so far regarding my work with the team. Steve Conklin helped me a lot in guiding me through the necessary tasks in the stable updates work.

Things I could do better

I'm glad when I'm able to fix user reported problems and contributing that upstream, and work on tooling and make sure the kernel updates are on track. Communicate better about this work I do probably is something I could make better, and it's what I feel lacking from me currently.

Plans for the future

General

I always try to maintain the better quality I can for the work I do, and plan to continue improving this, be it on tasks related to the maintenance of the linux kernel for Ubuntu or other related kernel task. Also improving always my skills where needed in order to better handle and fix any kernel problems which may appear.

What I like least in Ubuntu

I find the political structure inside the project a bit hard to follow at the start, and all membership levels and boards are confusing for newcomers I think, may be they could be simplified. I tend to not like bureaucracy like that, thinking that it also may hinder or scare new contributors, which may choose another project to contribute. But I have to admit that there may be good reasons the processes are as they are now, and for a huge project as Ubuntu to stay healthy and handle contributions they may be necessary.

General feedback

I have been reviewing and sponsoring Herton's packages for months. See his application above for a list of some of his sponsored kernel package uploads. His work is very high quality, and he has not truly needed a sponsor for a while now. Herton has also reviewed my kernel packages before upload, and caught errors that I have made.

His contributions to the tools used by the stable kernel team are a bit understated in his application - he has contributed significant new functionality in our workflow tools, and rapidly developed an understanding of the complexities of those tools.

He has a good sense of the responsibility required to deliver kernel packages, and the troubleshooting skills required to isolate problems. I trust him to deliver quality kernel packages for Ubuntu, and to ask when he has questions.

Specific Experiences of working together

I've enjoyed working with Herton. He works well with our team and with others, including the certification and QA teams. He is available during regular hours, and is very responsive to problems. A review of the bugs he has worked on and listed above will show that he can quickly work with bug reporters to isolate problems.

He has made mistakes, but he doesn't make the same mistake twice.

Areas of Improvement

I'm sure that as Herton's knowledge of the other areas of the Ubuntu 'ecosystem' and community increase, he'll contribute in those areas also. It's impossible to find areas in which you would say that he needs to improve, as he's moved rapidly to learn and constantly adjust his own processes and knowledge, and I'm sure this will continue.

General feedback

Herton and I worked together during the the Natty development cycle. We were both working on stable kernels for the Ubuntu Kernel Team. Herton prepared numerous kernel branches and packages. I reviewed quite a few of them.

I believe Herton to be diligent, trustworthy and very compitent. He has my complete confidence in the responsibility these upload rights grant him.
