This patch series takes care of a few cleanups for the page fragments API. First we do some renames so that things are much more consistent. First we move the page_frag_ portion of the name to the front of the functions names. Secondly we split out the cache specific functions from the other page fragment functions by adding the word "cache" to the name. Second I did some minor clean-up on the function calls so that they are more inline with the existing __free_pages calls in terms of how they operate. Finally I added a bit of documentation that will hopefully help to explain some of this. I plan to revisit this later as we get things more ironed out in the near future with the changes planned for the DMA setup to support eXpress Data Path. --- v2: Fixed a comparison between a void* and 0 due to copy/paste from free_pages I'm listing this as a patch for net or mm since I had originally submitted it against mm as that was where the patches for the __page_frag functions has previously resided. However they are now also in net, and I wanted to get this fixed before the merge window closed as I was hoping to make use of these APIs in net-next and I already have about 20 patches that are waiting on these patches to be accepted. I tried to get in touch with Andrew about this fix but I haven't heard any reply to the email I sent out on Tuesday. The last comment I had from Andrew against v1 was "Looks good to me. I have it all queued for post-4.9 processing.", but I haven't received any notice they were applied.
