From 61cc74fbb87af6aa551a06a370590c9bc07e29d9 Mon Sep 17 00:00:00 2001 From: Louis Rilling Date: Fri, 4 Dec 2009 14:52:41 +0100 Subject: block: Fix io_context leak after clone with CLONE_IO With CLONE_IO, copy_io() increments both ioc->refcount and ioc->nr_tasks. However exit_io_context() only decrements ioc->refcount if ioc->nr_tasks reaches 0. Always call put_io_context() in exit_io_context().
