    [$] Three ways to rework the swap subsystem

    Date:
    Mon, 07 Apr 2025 15:01:21 +0000

    Description:
    The kernel's swap subsystem is complex and highly optimized though not
    always optimized for today's workloads. In three adjacent sessions during
    the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, Kairui Song, Nhat Pham, and Usama Arif
    all talked about some of the problems that they are trying to solve in the Linux swap subsystem. In the first two cases, the solutions take the form of an additional layer of indirection in the kernel's swap map; the third,
    which enables swap-in of large folios, may or may not be worthwhile in the
    end.
