[RFC PATCH 0/5] introduce proc_inode->pid_entry

[Oleg Nesterov]

Hello,

Obviously not for inclusion. The patches are horrible, break task_nommu.c,
untested, etc. Only to explain what I mean and discuss the intent, at least.
On top of recent /proc/pid/*maps* cleanups I sent.

To me it looks a bit annoying that task_mmu.c needs 6 seq_operations's and
6 file_operations's to handle /proc/pid/*maps*. And _only_ because ->show()
differs.

Eric, et al, what do you think? At least something like 1-3 looks like a
good cleanup imho. And afaics we can do more cleanups on top.

Oleg.
