SubjectRe: [patch] proc: copy_to_user() returns unsigned
I got confused when I see the title of patch.
That's because I understood copy_to_user returns unsigned.
Please, change title to describe your patch.

[PATCH] proc : fix wrong usage of copy_to_user's return value.

Maybe you could name it well than me who is a not native English.
