26    scatter/gather DMA operations.
30    buffers are just as hard to use for DMA operations, but they can be
31    useful in situations where DMA is not available but virtually-contiguous
35    buffer can be unreliable on fragmented systems, but simpler DMA
289 same is normally true of contiguous-DMA drivers as well; videobuf will
293 play tricks by allocating DMA space at system boot time; videobuf does not
296 As of 2.6.31, contiguous-DMA drivers can work with a user-supplied buffer,
327 DMA; that ensures that the videobuf layer will not try to do anything with
336 For contiguous DMA drivers, the function to use is:
340 The contiguous DMA API goes out of its way to hide the kernel-space address
341 of the DMA buffer from drivers.
