From 002ef1dc63ded14507c110d3cf83d0c3f51374ab Mon Sep 17 00:00:00 2001 From: Ryan O'Hara Date: Wed, 21 Nov 2007 11:54:54 -0600 Subject: [PATCH] [GFS2] remove unnecessary permission checks Remove read/write permission() checks from xattr operations. VFS layer is already handling permission for xattrs via the xattr_permission() call, so there is no need for gfs2 to check permissions. Futhermore, using permission() for SELinux xattrs ops is incorrect.
