/proc/fs/afs/cells and /proc/fs/afs/rootcell are not new proc files, nor is the ability to configure the in-kernel afs filesystem by writing to them new. The cells file has been there since 2002 and the rootcell file before the start of the git history in 2005 - it's just that they've been in /proc/fs/afs/ not /proc/net/afs/.
However, the afs procfiles need to be somewhere under /proc/net/ for the network namespacing, so I moved the directory over and emplaced a symlink at /proc/fs/afs.
