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. McKenney <paulmck@linux.vnet.ibm.com> Cc: Greg KH <gregkh@linuxfoundation.org>
