David Vernet kicked off the BPF track at 2024’s BPF track at the
Linux Storage,
Filesystem, Memory Management, and BPF Summit
with a
talk about polymorphic kfuncs — or, with less jargon, kernel functions that can
be called from BPF which use different implementations depending on context.
He explained how this would be useful to
the sched_ext BPF scheduling framework,
but expected it to be helpful in
other areas as well.
