From 90af36022aecdeeb1b9c0755461187de717c86dd Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 5 Apr 2013 14:46:01 -0500 Subject: libceph: add, don't set data for a message Change the names of the functions that put data on a pagelist to reflect that we're adding to whatever's already there rather than just setting it to the one thing. Currently only one data item is ever added to a message, but that's about to change.
