I didn't, everything started when I explained to Gal why RDMA subsystem requires rdma-core counterpart for any UAPI code. https://lore.kernel.org/linux-rdma/CAFCwf12B4vCCwmfA7+VTUYUgJ9EHAtvg6F0bMYnsSCUBST+aWA@xxxxxxxxxxxxxx/T/#m17d52d61adadf54c12bfecf1af5db40f5d829ac3 And expressed my view on the quality of the library that was presented as open-source example. https://lore.kernel.org/linux-rdma/CAFCwf12B4vCCwmfA7+VTUYUgJ9EHAtvg6F0bMYnsSCUBST+aWA@xxxxxxxxxxxxxx/T/#m9059c5a9405ba932d9ffb731195a43b27443d265 > > Yes, when integrating into other subsystems (i.e. networking and rdma), > they should use those common subsystems interfaces, no one is arguing > that at all. > > totally lost, And here comes my request to do it right https://lore.kernel.org/linux-rdma/CAFCwf12B4vCCwmfA7+VTUYUgJ9EHAtvg6F0bMYnsSCUBST+aWA@xxxxxxxxxxxxxx/T/#ma1fa6fe63666f630674eb668f1c00e6a672db85b All that I asked from Oded is to do UAPI/libraries right, while all the responses can be summarized to one sentence - "it is too hard, we don't want to do it."
