It is really annoying to always have to loop through the entire

a single namespace in libnvme/nvme-cli.
So provide links to the namespace paths for efficient lookup.
I think having some form of links would be useful. Quite a while ago
Thadeu looked into adding some form of relationship for lsblk and
friends. Maybe it would be good to sync up and make sure whatever
links we are adding would be useful for all users?
Care to elaborate?
Using the block device name is the most straightforward way here; we
don't have a good enumeration to leverage as the paths are essentially
just a linked list.
We sure can have a subdirectory 'paths', and stick the links in there.
If that helps with lsblk ...
