Hi, since I'd like to have my python btrfs library work correctly for users with other systems than amd64, I have been looking at IOCTL number generation a bit. I just made something up in a branch, which follows the same way in which the IOC defines in kernel source are done: https://github.com/knorrie/python-btrfs/commits/ioctl The only other hardware than amd64 I have is a raspberry pi, which doesn't even seem to fall into the category having exceptions to the defaults... So, my question is: 1. am I still doing it wrong, or is this going into the right direction? 2. can you please test this branch if you have access to any of 'alpha', 'mips', 'powerpc', 'sparc', 'parisc' which runs a btrfs filesystem and let me know if this makes it possible to use the library (e.g. run some examples from the examples/ dir) 3. I also understand that there are difficulties for users who user 32 bit userland with a 64 bit kernel. - What is the exact technical reason for this? - What's the general opinion about this usecase? (needs to work, or, "doctor, if I push here it hurts; well, don't push there"...)
