Alexey Dobriyan e93b4ea20a proc: print more information when removing non-empty directories 
This usually saves one recompile to insert similar printk like below. :)

Sample nastygram:

remove_proc_entry: removing non-empty directory '/proc/foo', leaking at least 'bar'
------------[ cut here ]------------
