The three main components of this are: (1) dma-buf, representing a
sg_table and exposed to userspace as a file descriptor to allow passing
between devices, (2) fence, which provides a mechanism to signal when
-one device as finished access, and (3) reservation, which manages the
+one device has finished access, and (3) reservation, which manages the
shared or exclusive fence(s) associated with the buffer.
Shared DMA Buffers
- implements and manages operations in :c:type:`struct dma_buf_ops
<dma_buf_ops>` for the buffer,
- allows other users to share the buffer by using dma_buf sharing APIs,
- - manages the details of buffer allocation, wrapped int a :c:type:`struct
+ - manages the details of buffer allocation, wrapped in a :c:type:`struct
dma_buf <dma_buf>`,
- decides about the actual backing storage where this allocation happens,
- and takes care of any migration of scatterlist - for all (shared) users of
