ocfs2: add ocfs2_init_security in during file create
Security attributes must be set when creating a new inode. We do this in three steps. - First, get security xattr's name and value by security_operation - Calculate and reserve the meta data and clusters needed by this security xattr before starting transaction - Finally, we set it before add_entry Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
