if you really wish to mirror the linux /proc exactly but with ctl
files, this wouldn't be hard. i'd be tempted to do things lexically.
the path string is already held in the fid. just check if the fid's
path matches "/proc/[0-9]+" - if so, then allow userwalk and useropen of
"ctl", and amend rread() to add the extra entry in this case. there
should be enough space in the 64-bit qid path to have a uniquely
separate identifier for ctl files without impinging on linux inode
space.
