It’s obviously proprietary: it’s non-standard and specific to a single vendor.
I just re-read the LWN article and there's no suggestion of any such thing. Where are you seeing it?
Serving things to kernel from userland is decades old and commonly used with both NFS and iSCSI.
...and regular FC/SCSI too. I worked on that for four years. Yawn. What's your point?
The fact that this particular implementation uses io_uring instead of something non-proprietary like RDMA
RDMA implementations are even more likely to be bound up with proprietary bits than vanilla-TCP implementations. RDMA over IB or other even lesser known interconnects (both open/standard and proprietary) existed long before ROCE. Do you even know what "open" vs. "proprietary" mean? There were open network-disk protocols before iSCSI. I worked on such as early as 1989, and developed my own (along with my own user-space block device for Linux and Windows) in 2000. It seems like you've only been exposed to a small set of open/standards based technologies, and deride anything else as "proprietary" even though that's far from accurate. Is there some undisclosed interest at play here?
is just an implementation detail
It's a very important detail, considering the performance difference.
