| 2025-05-27 | bpf: Add open coded dmabuf iterator | T.J. Mercier | |
| This open coded iterator allows for more flexibility when creating BPF programs. It can support output in formats other than text. With an open coded iterator, a single BPF program can traverse multiple kernel data structures (now including dmabufs), allowing for more efficient analysis of kernel data compared to multiple reads from procfs, sysfs, or multiple traditional BPF iterator invocations.

| 2025-05-27 | bpf: Add dmabuf iterator | T.J. Mercier | |
| The dmabuf iterator traverses the list of all DMA buffers. DMA buffers are refcounted through their associated struct file. A reference is taken on each buffer as the list is iterated to ensure each buffer persists for the duration of the bpf program execution without holding the list mutex. Signed-off-by: T.J.
