From 81fe8c62febade6b5d0915269b06a0c50448da27 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten <hartleys@visionengravers.com> Date: Fri, 10 Jun 2011 14:59:05 -0700 Subject: [PATCH] ext3/ioctl.c: silence sparse warnings about different address spaces The 'from' argument for copy_from_user and the 'to' argument for copy_to_user should both be tagged as __user address space.
