Hi! Stefan Metzmacher asked whether I could package and upload liburing for Debian (and as a side effect Ubuntu). And here are some of the things I've noticed that would be nice to get fixed or improved before I upload it there. * The README states that the license is LGPL (I assume 2.1+ in contrast to 2.1?) and MIT, but there's at least one header that's GPL-2.0 + Linux-syscall-note, which I assume is due to it coming from the kernel headers. Would be nice to have every file with an explicit license grant, say at least with an SPDX tag, and update the README. * From the RPM spec file and the debian packaging in the repo, I assume there is no actual release tarball (didn't see on in kernel.dk nor kernel.org)? It would be nice to have one with a detached OpenPGP signature, so that we can include it in the Debian source package, to chain and verify the provenance from upstream. * The test suite fails for me on the following unit tests: read-write accept-link poll-many poll-v-poll short-read send_recv while running on Linux 5.5.0-rc0. I read from the README it is not supposed to work on old kernels, and might even crash them. But it would still be nice if these tests would get SKIPPED, so that I can enable them unconditionally to catch possible regressions and so they do not make the package fail to build from source on the Debian build daemons due to too old kernels, which in most cases will be one from a Debian stable release (Linux 4.19.x or so). There are a couple of issues with the build system, for which I'll be sending out a couple of patches later. Thanks, Guillem
