From 249ca1a86067e6a4198f7b2b7e19b505e2f41864 Mon Sep 17 00:00:00 2001 From: Taeung Song Date: Tue, 30 Jun 2015 17:15:21 +0900 Subject: perf kmem: Fill in the missing session freeing after an error occurs When an error occurs an error value is just returned without freeing the session. So allocating and freeing session have to be matched as a pair even if an error occurs.
