From: Mimi Zohar <zohar@linux.vnet.ibm.com>

commit e2598077dc6a26c9644393e5c21f22a90dbdccdb upstream.

Intermittently security.ima is not being written for new files. This
patch re-initializes the new slab iint->atomic_flags field before
freeing it.

Fixes: commit 0d73a55208e9 ("ima: re-introduce own integrity cache lock")
