Here is a series of patches to make the procfs internals private to the procfs
filesystem. This is built on top of the patches to eliminate
create_proc_read_entry() after the kill-read_proc_t tag.
These patches include fixes for the places that are attempting to abuse
proc_dir_entry->count and doing it incorrectly because PID namespaces now
exist.
All accesses to the PDE struct have been replaced with out-of-line accessor
functions. This is a bit less efficient than it used to be, but this could be
mitigated by using inode->i_private.
The internal procfs structs have moved to fs/procfs/internal.h. Some of the
remaining stuff in linux/proc_fs.h has been split out to linux/kcore.h and
linux/proc_ns.h as they's separate specialised intefaces.
These patches can be seen here also:
