Subject: [PATCH 3/4] rcu: Update TREE05.boot to test normal synchronize_rcu()
Date: Thu, 23 Jan 2025 19:58:27 +0100	[thread overview]
Message-ID: <20250123185828.460836-3-urezki@gmail.com> (raw)
In-Reply-To: <20250123185828.460836-1-urezki@gmail.com>

Add extra parameters for rcutorture module. One is the "nfakewriters"
which is set -1. There will be created number of test-kthreads which
correspond to number of CPUs in a test system. Those threads randomly
invoke synchronize_rcu() call.

Apart of that "rcu_normal" is set to 1, because it is specifically for
a normal synchronize_rcu() testing, also a newly added parameter which
is "rcu_normal_wake_from_gp" is set to 1 also. That prevents interaction
with other callbacks in a system.
