Hello everyone, This is a follow up patchset to the driver I sent an email about a few weeks ago [0]. I understand this patchset will probably get rejected, but I wanted to report on what I have done thus far. I have got the upstream module imported and building, and it passes some basic tests so far (I have not tried getting XFS/FStests running yet). Like mentioned earlier, some of the files have been moved to folios, but a large majority of them still use bufferheads. I would like to have them completely removed before moved from staging/ into fs/. I have split everything up into separate commits as best as I could. Most of the C files rely in functions from other C files, so I included them all in one patch/commit. I am curious to hear everyone's thoughts on this and to start getting the ball rolling for the code-review process. Please feel free to include/CC anyone who may be interested in this driver/the review process. I have included a few people, but have certainly missed others.
