Subject: [PATCH 3.16 107/346] tools/vm/slabinfo: fix an unintentional printf

3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 2d6a4d64812bb12dda53704943b61a7496d02098 upstream.

The curly braces are missing here so we print stuff unintentionally.

Fixes: 9da4714a2d44 ('slub: slabinfo update for cmpxchg handling')
