This one is going to need multiple phases, and in a moment you're going to understand what all functions called into libxfs should have a "libxfs define wrapper": 1. sync up to kernel commit before error negation 2. make sure all external function calls have libxfs define wrappers 3. commit error negation patch and change sign of all libxfs define wrappers 4. apply kernel libxfs rename patch and restructure libxfs userspace and xfsprogs build to match 5. continue syncing kernel changes commit by commit. Given the scope of changes, and the fact that some of the changes have already been applied (i.e. bug fixes, finobt changes, etc) step #1 is not going to be a straight forward commit-by-commit. So I'm happy to do that as a bulk commit. Steps #2 and #3 are relatively straight forward, too, just a bit painful as we need to be sure we don't leak negative errors. Step #4 is the big one; we want to end up with the kernel fs/xfs/libxfs to be identical to the xfsprogs:/libxfs/ code and so in userspace we've got to move headers around and rejig includes and things like that. That's one I should probably do. And from there, step 5 should be a simple extract/sed/commit process of pulling patch by patch from the kernel changes that touch fs/xfs/libxfs.... So, really, the big step right now is #1...
