Subject: [PATCH tip/core/rcu 15/18] torture: Allow scenarios to be specified to torture.sh
Date: Wed,  6 Jan 2021 09:31:16 -0800
Message-ID: <20210106173119.23159-15-paulmck@kernel.org> (raw)
In-Reply-To: <20210106173056.GA23035@paulmck-ThinkPad-P72>

From: "Paul E. McKenney" <paulmck@kernel.org>

This commit adds --configs-rcutorture, --configs-locktorture, and
--configs-scftorture arguments to torture.sh, allowing the desired
set of scenarios to be passed to each.  The default for each has been
changed from a large-system-appropriate set to just CFLIST for each.
Users are encouraged to create scripts that provide appropriate settings
for their specific systems.
