ima: add inode_post_setattr call
Changing an inode's metadata may result in our not needing to appraise the file. In such cases, we must remove 'security.ima'. Changelog v1: - use ima_inode_post_setattr() stub function, if IMA_APPRAISE not configured Signed-off-by: Mimi Zohar <zohar@us.ibm.com> Acked-by: Serge Hallyn <serge.hallyn@ubuntu.com> Acked-by: Dmitry Kasatkin <dmitry.kasatkin@intel.com>
