If it is not tightly linked to the kernel and is just a normal
library, you might consider using github. This is what we do for the
rdma user space and it works well. We still take patches from the
mailing list flow, but do use a fair amount of the github stuff too:

https://github.com/linux-rdma/rdma-core

With github actions now able to provide a quite good CI it covers a
lot of required stuff for a library in one place, in a way that
doesn't silo all the build infrastucture.

If you are interested in how we set it up I can write a longer email.
