    [$] Using dma-bufs for read and write operations

    Description:
    The kernel's dma-buf
    subsystem provides a way for drivers to share memory buffers, usually
    in order to support efficient device-to-device I/O . At the 2026 Linux Storage,
    Filesystem, Memory Management, and BPF Summit , Pavel Begunkov, assisted
    by Kanchan Joshi, led a joint session of the storage and memory-management tracks to explore ways to make the use of dma-bufs more efficient yet, and
    to make them available for read and write operations initiated by user
    space.
