Self-Driving DAMON/S: Controlled and Automated Access-aware Efficient Systems - SeongJae Park, Meta

Wednesday June 25, 2025 11:00am - 11:40am MDT

Bluebird Ballroom 2B

Data access monitoring and access-aware system operations based on it can be very useful and efficient when it is used wisely. Otherwise, it can be useless or even harmful. Hence, users are often required to do time-consuming and repetitive testing and tuning. It is not only data access monitoring's problem but a common issue at system-level operations.

DAMON is a Linux kernel subsystem for efficient data access monitoring and access-aware system operations. It mitigates the tuning problem by embedding a few automation mechanisms that allows users to run it in an automated for best outputs, but still safely controlled way.

This talk introduces the tuning problem and DAMON's automation mechanisms in detail, with usage guidelines and evaluation results. Audiences will be able to understand how they can use DAMON for more efficient system, and get some ideas about how to solve the tuning problems in general.

Can File Systems Survive in Data-centric World? - Viacheslav Dubeyko, IBM

Wednesday June 25, 2025 2:10pm - 2:50pm MDT

Bluebird Ballroom 2B

The volume of processing data is growing exponentially. AI/ML algorithms, financial transactions, social networks, cloud computing represent modern trends that latency, performance sensitive, and data hungry. File systems represent crucial and fundamental technology that builds foundation of data storage stack. However, pressure of data-centric and data-intensive nature of modern applications revealed significant overhead that file systems introduce in data storage stack. Moreover, massive amount of hardware accelerator and kernel bypassing technologies, dis-aggregated architecture, ultra-fast storage devices create “illusion” or “impression” that file systems could be a redundant item of data storage stack. Can file systems survive in data-centric world?

An Investigation of Patch Porting Practices of the Linux Kernel Ecosystem - Xingyu Li, UC Riverside

Wednesday June 25, 2025 4:20pm - 5:00pm MDT

Bluebird Ballroom 2B

The Linux ecosystem—spanning upstream mainline, stable and LTS branches, and downstream distributions like Ubuntu and Android—relies on patch porting to ensure stability and security. However, concerns persist about delayed or incomplete patch propagation. By mining software repositories across 28 Linux branches (e.g., Android,Ubuntu,Debian,OpenSLE and etc) and 584K patches., we uncover diverse patch porting strategies and their trade-offs, measured through patch delay, patch rate, and bug inheritance ratio. We also analyze the factors influcing the patch porting practices and offer actionable insights to enhance patch flow efficiency and strengthen the Linux ecosystem.

Xingyu Li

PhD candidate; Research assistant, UC Riverside

I am a final year PhD student in UC Riverside in computer science. I am working on improving Linux kernel security by investigating Linux patch porting strategy, identifying silent serious patches and improving fuzzing efficiency.
