Subject: [PATCH 4.12 130/196] ubifs: Dont encrypt special files on creation

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Gstir <david@...ma-star.at>

commit f34e87f58dabc31eb69f61cf4a79e951d4176743 upstream.

When a new inode is created, we check if the containing folder has a encryption
policy set and inherit that. This should however only be done for regular
files, links and subdirectories. Not for sockes fifos etc.

Fixes: d475a507457b ("ubifs: Add skeleton for fscrypto")
