What is the proc_base_stuff[] nonsense about? AFAICS, that
went in with no reason whatsoever in

Rationale is very weak and patch adds considerable complexity
for no good reason. Besides, it's obfuscated just for the hell of it:
if (!IS_ERR(result) || PTR_ERR(result) != -ENOENT)
instead of
if (result != ERR_PTR(-ENOENT))
etc.

Unless there are _real_ plans that would justify that animal,
I'm going to get rid of it in the pending patch series (/proc/self
cleanups, saner dentry retention for non-process parts, etc.).
