Subject: [PATCH RFC LKMM 6/7] EXP tools/memory-model: Make scripts take "-j" abbreviation for "--jobs"
Date:   Wed, 29 Aug 2018 14:10:52 -0700
In-Reply-To: <20180829211018.GA19646@linux.vnet.ibm.com>
References: <20180829211018.GA19646@linux.vnet.ibm.com>
Message-Id: <20180829211053.20531-6-paulmck@linux.vnet.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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".
