Subject: workqueue: fix uninitialized next pointer
X-Git-Url: http://git.liburcu.org/?p=userspace-rcu.git;a=commitdiff_plain;h=db9916c6618c4da50d5f2779af1640cab1ebcfed

workqueue: fix uninitialized next pointer

We use this next pointer to check if the worker in in the wait queue or
not. Therefore, we need to initialize it to NULL.
