David VERNET

David is a kernel engineer at Meta, working primarly on the CPU scheduler and BPF. He, along with coworkers at Meta, maintain the sched_ext pluggable scheduling framework, and the scx_rusty scheduler. In his free time David is the co-chair for the IETF BPF standardization working group, and also likes to stargaze, brew (and drink) beer, and be terrible at golf.

Steven ROSTEDT

Steven ROSTEDT

Steven Rostedt is the main developer and maintainer of ftrace, the official tracer of the Linux kernel, as well as the user space tools trace-cmd, the ftrace tracing libraries and co-maintainer of KernelShark. Steven is one of the original developers of the Real Time patch (PREEMPT_RT) and continues his role leading the team that maintain the Real Time patch (PREEMPT_RT) stable releases. He also develops ktest.pl (in the kernel source) and created the Linux kernel “make localmodconfig” option.

Andrii NAKRYIKO

Andrii NAKRYIKO

Andrii Nakryiko is a Software Engineer at Meta. He’s one of BPF maintainers and focuses on BPF ecosystem development both from kernel side, working on BPF verifier, BPF CO-RE, and kernel tracing infrastructure, as well as in user space, developing libbpf library and helping users with kernel tracing and observability projects.

Paul MCKENNEY

Paul MCKENNEY

Paul E. McKenney has been coding for almost four decades, more than half of that on parallel hardware, where his work has earned him a reputation among some as a flaming heretic. Over the past decade, Paul has been an IBM Distinguished Engineer at the IBM Linux Technology Center. Paul maintains the RCU implementation within the Linux kernel, where the variety of workloads present highly entertaining performance, scalability, real-time response, and energy-efficiency challenges. Prior to that, he worked on the DYNIX/ptx kernel at Sequent, and prior to that on packet-radio and Internet protocols (but long before it was polite to mention Internet at cocktail parties), system administration, business applications, and real-time systems. His hobbies include what passes for running at his age (also knows as “hiking”) along with the usual house-wife-and-kids habit.

Jens AXBOE

Jens AXBOE

Jens Axboe is Software Engineer at Facebook, formerly a Fellow at Fusion-io, and Consulting member of staff at Oracle. He also serves as the Linux block layer maintainer. Jens has worked on all things Linux IO related, such as data writeback, IO scheduling, SATA/SCSI, and others. Most recently his interests have been centered around making super fast flash based devices work and scale well in the kernel.

Breno LEITAO

Breno LEITAO

Breno Leitao has been involved in Linux development since 1997, contributing to various aspects of the operating system. His current focus is on enterprise Linux deployment, specifically on improving the process of rolling out upstream kernels to millions of servers. Breno’s aim is to streamline this bleeding edge large-scale deployment, making it less painful.

Vlastimil BABKA

Vlastimil BABKA

Vlastimil works as a kernel developer at SUSE Labs, focusing on the memory management subsystem. He currently maintains the remaining slab allocator implementation after deleting the other two. He’s also interested in the page allocator, memory reclaim and compaction, debugging features, and investigating kernel crash dumps.

Guilherme Amadio is a member of the storage group in the IT department at CERN. He currently works as a service manager for EOS, providing storage services for physics experiments, and on the development of both EOS and XRootD projects. In the past, as a member of the Experimental Physics (EP) department, Guilherme has also worked on performance optimization of detector simulation software (Geant4), on research for porting simulation onto GPUs, and on the ROOT data analysis  framework. Guilherme is a Gentoo Linux developer since 2015. There, he maintains packages for perf, and for scientific  software such as ROOT, Geant4, and related packages.

Sebastian ANDRZEJ

Sebastian ANDRZEJ

Sebastian first started to contribute to the Linux kernel in the crypto subsystem. Since then he looked into other subsystem including the USB stack. He sent a few patches to RT-tree which he started maintaining around the v3.10 series. Besides kernel development he is also a Debian Developer and maintains a few user spaces packages.
