Post Syndicated from corbet original https://lwn.net/Articles/1072367/

When Brendan Jackman proposed
a session for the 2026 Linux Storage,
Filesystem, Memory Management, and BPF Summit
, his topic was “a
pagetable library for the kernel
“. During the actual
memory-management-track session, though, he stated that the idea had
fizzled” and he was going to cover related topics instead. What
resulted was a session on ways to efficiently manage pages that are not
present in the kernel’s direct map.
