3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Benjamin LaHaise <bcrl@xxxxxxxxx> commit 1881686f842065d2f92ec9c6424830ffc17d23b0 upstream. e34ecee2ae791df674dfb466ce40692ca6218e43 reworked the percpu reference counting to correct a bug trinity found. Unfortunately, the change lead to kioctxes being leaked because there was no final reference count to put. Add that reference count back in to fix things.
