Subject: Fix: rcutorture should register thread using call_rcu
X-Git-Tag: v0.9.3~2
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=fcb81146d096d63d39adde4f790465a5c52999bb;p=userspace-rcu.git

Fix: rcutorture should register thread using call_rcu

From rcu-api.txt:

`call_rcu` should be called from registered RCU read-side threads.
For the QSBR flavor, the caller should be online.
