Can you explain why "filesystem foo uses device bar" gives an object associated with bar and "process baz has bar opened" doesn't?
"Associated with" is asymmetric in this case - just as for files and processes holding them opened. We do have objects for process->file (/proc/<pid>/fd/*) and we certainly don't have anything like that for other direction.
That's what I'm asking about - do we want to have objects on the _partition_ side of things that would require per-partition directory? Not on the filesystem/swap/whatnot side...
