Kui-Feng Lee spoke early in the BPF track at the 2024
Linux Storage,
Filesystem, Memory Management, and BPF Summit
about some of the
recent improvements to BPF. These changes were largely driven by the
sched_ext work that David Vernet had covered in
the previous talk
. Lee focused on changes relevant to struct_ops
programs, but several of those changes apply to all BPF programs.
