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.
