Each year, we look forward to gathering at Linux Storage, Filesystem, Memory Management, and BPF Summit to share information, collaborate, and learn together. Due to continual assessments and growing concerns around COVID-19, we have made the decision to cancel Linux Storage, Filesystem, Memory Management, and BPF Summit this year. Next year the summit will be held in Palm Springs, on May 12-14, 2021 at the Riviera Palm Springs. A new CFP and registration will be held again, along with a new round of invites. The program committee will remain the same, and next year we will choose new members. Event Registration The Linux Foundation will take care of canceling all event registrations - you do not need to do anything. We thank you for your patience and understanding while we work through this very fluid situation. A great deal of work and preparation has gone into the information and content planned to be delivered at LSFMMBPF and we look forward to sharing it all with our community next year. Thank you again for your support. Our sincere sympathies are with all those being affected and we wish for good health and safety for all. Thank you on behalf of the program committee: Josef Bacik (Filesystems) Amir Goldstein (Filesystems) Martin K. Petersen (Storage) Omar Sandoval (Storage) Michal Hocko (MM) Dan Williams (MM) Alexei Starovoitov (BPF) Daniel Borkmann (BPF)
