From e16acb503b42ef241a9396de7c5a1614c74d8ca6 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 20 Nov 2009 16:08:58 -0800 Subject: [PATCH] sysfs: sysfs_setattr remove unnecessary permission check. inode_change_ok already clears the SGID bit when necessary so there is no reason for sysfs_setattr to carry code to do the same, and it is good to kill the extra copy because when I moved the code last in certain corner cases the code will look at the wrong gid.
