Creates a new dma_buf, and associates an anon file with this buffer, so it can be exported. also connect the allocator specific data and ops to the buffer. additionally, provide a name string for exporter; useful in debugging.
struct dma_buf * dma_buf_export_named(void * priv, const struct dma_buf_ops * ops, size_t size, int flags, const char * exp_name);
priv
[in] Attach private data of allocator to this buffer
ops
[in] Attach allocator-defined dma buf ops to the new buffer.
size
[in] Size of the buffer
flags
[in] mode flags for the file.
exp_name
[in] name of the exporting module - useful for debugging.
Returns, on success, a newly created dma_buf object, which wraps the supplied private data and operations for dma_buf_ops. On either missing ops, or error in allocating struct dma_buf, will return negative error.
