Hello there,

You can see the available branches by replacing git:// with https:// i.e.:
https://git.infradead.org/nvme.git

The branch is called nvme-5.12

It is not out-of-tree kernel code, it is a subsystem git tree,
so you build the kernel like usual.

If you already have a kernel git tree somewhere,
simply add an additional remote, and it should be quick:

$ git remote add nvme git://git.infradead.org/nvme.git && git fetch nvme


Kind regards,
Niklas
