From c51d7b5e6c94aa6b554c27bd2b0eb64ebef02334 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 3 Oct 2018 17:25:33 -0700 Subject: rcutorture: Print time since GP end upon forward-progress failure If rcutorture's forward-progress tests fail while a grace period is not in progress, it is useful to print the time since the last grace period ended as a way to detect failure to launch a new grace period. This commit therefore makes this change. Signed-off-by: Paul E.
