Date: Sat, 18 Sep 2010 12:13:40 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Dan Carpenter <error27@...il.com>, Chris Wilson <chris@...is-wilson.co.uk> Subject: [122/129] i915_gem: return -EFAULT if copy_to_user fails 2.6.35-stable review patch. If anyone has any objections, please let us know. ------------------ From: Dan Carpenter <error27@...il.com> commit c877cdce93a44eea96f6cf7fc04be7d0372db2be upstream. copy_to_user() returns the number of bytes remaining to be copied and I'm pretty sure we want to return a negative error code here.
