From c0ee4500ff67e455dcbc74ff3e9e9faa3bc93be1 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 10 Apr 2017 13:49:03 -0700 Subject: [PATCH] rcutorture: Add a scenario for Classic SRCU A robust combination of paranoia and cowardice has resulted in retaining Classic SRCU (CONFIG_CLASSIC_SRCU) as a backup for the shiny new Tiny and Tree SRCU implementations. If it is to be a viable backup, it of course needs to be tested. This commit therefore adds an rcutorture scenario named SRCU-C for Classic SRCU. This commit also adds this scenario to the set that are run by default. Once sufficient good experience has accumulated for Tiny and Tree SRCU, this test will be removed, along with the Classic SRCU implementation itself. Signed-off-by: Paul E.
