From 27fa83852ba275361eaa1a1283cf6704fa8191a6 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Thu, 14 Feb 2013 12:16:43 -0600 Subject: libceph: isolate other message data fields Define ceph_msg_data_set_pagelist(), ceph_msg_data_set_bio(), and ceph_msg_data_set_trail() to clearly abstract the assignment of the remaining data-related fields in a ceph message structure. Use the new functions in the osd client and mds client.
