Subject: [PATCH] ima: re-initialize iint->atomic_flags
Date: Tue, 23 Jan 2018 11:59:23 -0500	[thread overview]
Message-ID: <1516726763.3615.2.camel@linux.vnet.ibm.com> (raw)

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")
Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
