Name

dma_buf_put — decreases refcount of the buffer

Synopsis

void dma_buf_put (struct dma_buf * dmabuf);
 

Arguments

dmabuf

[in] buffer to reduce refcount of

Description

Uses file's refcounting done implicitly by fput.

If, as a result of this call, the refcount becomes 0, the 'release' file operation related to this fd is called. It calls dma_buf_ops.release vfunc in turn, and frees the memory allocated for dmabuf when exported.
