| |
In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h.
Some reasons why this API should be removed have been given by Julia Lawall in [2].
Finally, Arnd Bergmann reminded that the documentation was updated 11 years ago to only describe the modern linux/dma-mapping.h interfaces and mark the old bus-specific ones as no longer recommended, see commit 216bf58f4092 ("Documentation: convert PCI-DMA-mapping.txt to use the generic DMA API").
A coccinelle script has been used to perform the needed transformation Only relevant parts are given below.
