From 7a627e3b9a2bd0f06945bbe64bcf403e788ecf6e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 10 May 2011 15:34:16 -0700 Subject: SELINUX: add /sys/fs/selinux mount point to put selinuxfs In the interest of keeping userspace from having to create new root filesystems all the time, let's follow the lead of the other in-kernel filesystems and provide a proper mount point for it in sysfs. For selinuxfs, this mount point should be in /sys/fs/selinux/ Cc: Stephen Smalley Cc: James Morris Cc: Eric Paris Cc: Lennart Poettering Cc: Daniel J Walsh Signed-off-by: Greg Kroah-Hartman [include kobject.h - Eric Paris] [use selinuxfs_obj throughout - Eric Paris] Signed-off-by: Eric Paris --- security/selinux/selinuxfs.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'security') diff --git a/security/selinux/selinuxfs.c b/security/selinux/selinuxfs.c index 973f5a4a6fc..fde4e9d64bf 100644 --- a/security/selinux/selinuxfs.c +++ b/security/selinux/selinuxfs.c @@ -28,6 +28,7 @@ #include #include #include +#include /* selinuxfs pseudo filesystem for exporting the security policy API.
