McKenney" Date: Sun, 6 Dec 2015 20:20:14 -0800 Subject: rcutorture: Don't keep empty console.log.diags files Currently, an error-free run produces an empty console.log.diags file. This can be annoying when using "vi */console.log.diags" to see a full summary of the errors. This commit therefore removes any empty files during the analysis process. Signed-off-by: Paul E.
