Subject: [PATCH 2/4] lnvm: do not print 0 when the arg is not given
In-Reply-To: <20190721152649.4894-2-minwoo.im.dev@gmail.com>
References: <20190721152649.4894-1-minwoo.im.dev@gmail.com>

Message-ID: <20190721152649.4894-3-minwoo.im.dev@gmail.com>

If an argument is not given by the user, it just needs to show the
situation, not a prominent 0 which indicates the size of the argument
variable.
