NAME
dma_buf_vmap - Create virtual mapping for the buffer object into kernel address space. Same restrictions as for vmap and friends apply.
SYNOPSIS
void * dma_buf_vmap(struct dma_buf * dmabuf);
ARGUMENTS
dmabuf [in] buffer to vmap
DESCRIPTION
This call may fail due to lack of virtual mapping address space. These calls are optional in drivers. The intended use for them is for mapping objects linear in kernel space for high use objects. Please attempt to use kmap/kunmap before thinking about these interfaces.
