Subject: UBI: Don't exit from ubi_thread until kthread_should_stop() is true
X-Git-Tag: v2.6.28-rc7~51^2
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=2ad49887150894b9ed6a87a76b409adceee6b074;p=linux-2.6-omap-h63xx.git

UBI: Don't exit from ubi_thread until kthread_should_stop() is true

If ubi_thread() exits but kthread_should_stop() is not true
then kthread_stop() will never return and cleanup thread
will forever stay in "D" state.
