Steven Rostedt is one of the original developers of the PREEMPT_RT patch; he started working in 2004 with the goal of turning Linux into a Real Time designed operating system. Although, the PREEMPT_RT patch still exists out of tree, several of its features have made it into the vanilla kernel. One of these features being Ftrace, the official tracer of Linux. Steven is the main author, developer and maintainer of Ftrace. He has also created ktest.pl, which is a testing framework within the Linux kernel, and is the one responsible for the kernel build option “make localmodconfig”. Outside of development, Steven has done numerous presentations around the world. He’s also been on the Kernel Summit program committee from 2010-2016, and is currently one the Linux Foundation’s Technical Advisory Board (TAB) members, which represents the kernel community to the foundation.
Steven joined VMware at the start of 2017 as one of the core developers at the heart of VMware’s Open Source Technology Center, focused on providing value and leadership in spreading open source expertise and culture across the company. Through VMware, Steven continues to work with various open source communities contributing his time to develop and enhance open source software.

Enric Balletbò i Serra
Enric is an Embedded Linux Software Engineer for Collabora Ltd. working with major Industrial and Consumer customers. He has 10 years experience helping in the design and bringing up Computer on Modules (CoM) and System on Modules (SoM), mostly based on ARM processors running Linux. He currently maintains some of them in mainline Linux and is an active upstream contributor. Enric has a degree in Electronic Engineering from the University of Barcelona, and from the beginning has been interested in the Open Source world, especially in the Linux kernel. Both interests have allowed him to grow and get a deeper into the knowledge of the ‘Thin Red Line’ between software and hardware.
Rafael maintains the Linux kernel’s power management infrastructure and the core ACPI support code. He works at Intel Open Source Technology Center and focuses on the mainline Linux kernel development. He has been actively contributing to Linux since 2005, in particular to the kernel’s suspend/hibernate subsystem, power management in general (IO runtime PM framework, CPUFreq, CPUIdle, PM QoS, system wakeup framework etc.), hot-plug infrastructure, core ACPI support, core PCI support and more. Before joining Intel he worked at the Faculty of Physics of the University of Warsaw as a lecturer and IT specialist, he was a Linux and IT consultant and he ran a business of his own. Rafael holds a PhD in Physics from the University of Warsaw.
