From: Thierry Reding Subject: [PATCH] ext2: Don't export ext2_mask_flags() to user space Date: Wed, 21 Mar 2012 22:50:07 +0100 Message-ID: <1332366608-2695-1-git-send-email-thierry.reding@avionic-design.de> Cc: Al Viro , Jan Kara , linux-ext4@vger.kernel.org, stable@vger.kernel.org To: linux-kernel@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-ext4.vger.kernel.org Using the exported linux/ext2_fs.h header from user space is broken since commit 0583fcc because the umode_t type is no longer exported. This happens for example when compiling busybox' tune2fs applet. The e2fsprogs package does not have this problem because it ships with its own header and doesn't use the one exported by the Linux kernel. However, since busybox doesn't use the ext2_mask_flags() function the easiest fix is to just not export it and as a result the umode_t type definition is longer needed.
