[$] Inlining kfuncs into BPF programs
Eduard Zingerman presented a daring proposal that "makes sense if you think
about it a bit" at the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit. He wants to inline
performance-sensitive kernel functions
into the BPF programs that call them. His
prototype does not yet address all of the design problems inherent in that idea,
but it did spark a lengthy discussion about the feasibility of his proposal.
