GET_DMA_BUF(9)                    Device drivers infrastructure                    GET_DMA_BUF(9)



NAME
       get_dma_buf - convenience wrapper for get_file.

SYNOPSIS
       void get_dma_buf(struct dma_buf * dmabuf);

ARGUMENTS
       dmabuf
           [in] pointer to dma_buf

DESCRIPTION
       Increments the reference count on the dma-buf, needed in case of drivers that either need
       to create additional references to the dmabuf on the kernel side. For example, an exporter
       that needs to keep a dmabuf ptr so that subsequent exports don't create a new dmabuf.
