[$] Efficient access to local storage for BPF programs

When a BPF program is used to filter or redirect packets in the networking
subsystem, the program will often want to associate data with each packet as it
moves through the kernel. The kernel's
that end
in STORAGE.)
Amery Hung and Jakub Sitnicki led two sessions
at the 2026

Linux Storage, Filesystem, Memory-Management, and BPF Summit
about how to make accesses to local storage data more efficient. Hung spoke
about general performance problems related to locking, while Sitnicki examined
the use of local storage in the networking subsystem in particular.
