Subject[PATCH memory-model 3/3] EXP tools/memory-model: Make scripts take "-j" abbreviation for "--jobs"
Date
From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com>

The "--jobs" argument to the litmus-test scripts is similar to the "-jN"
argument to "make", so this commit allows the "-jN" form as well. While
in the area, it also prohibits the various forms of "-j0".

Suggested-by: Alan Stern <stern@rowland.harvard.edu>
