From 9516e45b25d9967c35d2e798496ec5e590aaa24f Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 1 Mar 2013 18:00:16 -0600 Subject: [PATCH] libceph: simplify new message initialization Rather than explicitly initializing many fields to 0, NULL, or false in a newly-allocated message, just use kzalloc() for allocating new messages. This will become a much more convenient way of doing things anyway for upcoming patches that abstract the data field.
