McKenney <paulmck@xxxxxxxxxx> CommitterDate: Mon, 08 Mar 2021 14:23:01 -08:00 torture: Allow 1G of memory for torture.sh kvfree testing Yes, I do recall a time when 512MB of memory was a lot of mass storage, much less main memory, but the rcuscale kvfree_rcu() testing invoked by torture.sh can sometimes exceed it on large systems, resulting in OOM. This commit therefore causes torture.sh to pase the "--memory 1G" argument to kvm.sh to reserve a full gigabyte for this purpose. Signed-off-by: Paul E.
