From f43f8f73510c1013fe9449d7732e8f73a75b6fde Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sat, 19 Oct 2013 06:28:21 -0700 Subject: rcutorture: Record results from repeated runs of the same test scenario Repeatedly running a given test, for example, by repeating the name as in "--configs "TREE08 TREE08 TREE08" records the results only of the last run of this test. This is because the earlier results are overwritten by the later results. This commit therefore checks for earlier results, using numbered file extensions to distinguish multiple runs. The earlier example would therefore create directories TREE01, TREE01.2, and TREE01.3. Signed-off-by: Paul E.
