Subject: [PATCH ghak21 V2 3/4] audit: add refused symlink to audit_names
Date:   Mon, 12 Mar 2018 02:31:19 -0400

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Audit link denied events for symlinks had duplicate PATH records rather
than just updating the existing PATH record.  Update the symlink's PATH
record with the current dentry and inode information.
