Subject: Fix: rcutorture should register thread using call_rcu
X-Git-Tag: v0.10.0~20
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=a13ef613168a4f5f35ca820750fedf13c403ce98;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.
