From 0e7457b550233314394574c6bdc890de9131daf5 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 28 Jan 2021 10:15:02 -0800 Subject: [PATCH] rcuscale: Disable verbose torture-test output Given large numbers of threads, the quantity of torture-test output is sufficient to sometimes result in RCU CPU stall warnings. The probability of these stall warnings was greatly reduced by batching the output, but the warnings were not eliminated. However, the actual test only depends on console output that is printed even when rcuscale.verbose=0. This commit therefore causes this test to run with rcuscale.verbose=0. Signed-off-by: Paul E.
