Subject: [PATCH v1 05/11] gen_init_cpio: replace inline format string with common variable
Date: Tue, 20 Jan 2015 14:12:54 -0500 [thread overview]
Message-ID: <1421781180-24425-6-git-send-email-zohar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1421781180-24425-1-git-send-email-zohar@linux.vnet.ibm.com>
The same printf format string is used in a number of places. This
patch replaces the inline format string with a single common variable
called newcfmt.
