From 1f32ee65864830e326aae5890780fa630423a8e9 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 27 Sep 2016 11:56:12 -0700 Subject: [PATCH] torture: Prevent jitter from delaying build-only runs Currently, if the --jitter flag specifies jitter for a --build-only run, the system will obediently build a kernel, refuse to launch it, launch the requested number of jitter processes, and wait for the specified kernel run time, which defaults to 30 minutes. This is of course quite pointless. This commit therefore disables jitter on build-only runs. Signed-off-by: Paul E.
