LWN Coverage of the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit
- Buffered atomic writes, writethrough, and more: a multi-slot session on the path toward buffered atomic writes for PostgreSQL and others
- Keeping COWs in context (a.k.a. anonymous reverse mapping): an attempt to update and simplify the kernel's reverse-mapping code.
- Policy groups for the kernel: is there a better interface for the administration of policies that don't fit the control-group model?
- HugeTLB preservation over live update: how to support the goal of swapping out the kernel on a running system while preserving the huge pages used by virtual machines running on that system.
- Controlling memory management with BPF: what might be possible by integrating BPF with the memory-management subsystem, and the obstacles to doing that.
- Swap tables, flash-friendly swap, swap_ops, and more: three sessions on the present and future state of the kernel's swap subsystem.
- Improving the per-CPU memory allocator: an allocator that is meant to improve scalability has scalability problems of its own.
- What's brewing in CXL: developments in the quest to support Compute Express Link (CXL) devices in the kernel.
- What is to be done about MGLRU?: the kernel has two separate reclaim implementations, one of which is the multi-generational LRU; how can those two be unified into one?
- In search of faster this_cpu operations: a scheme to make per-CPU variables faster on non-x86 architectures.
