Alexey Dobriyan 4b98d11b40 [PATCH] ifdef ->rchar, ->wchar, ->syscr, ->syscw from task_struct 
They are fat: 4x8 bytes in task_struct.
They are uncoditionally updated in every fork, read, write and sendfile.
They are used only if you have some "extended acct fields feature".

And please, please, please, read(2) knows about bytes, not characters,
why it is called "rchar"?
