I am not sure this matches up to the desire for 1 value per file. What I
thought we wanted was a directory for each path, so it'd look something
like:

 /sys/block/nvme0n1/multipatch/nvme0c0n1/
 /sys/block/nvme0n1/multipatch/nvme0c3n1/

And each directory has their attributes so they print exactly one value
instead of the multi-line output. You'd know which path the output
corresponds to from the file's directory.
