From 8f3bc053c610826a657714649ea596f07875db2e Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Wed, 14 Oct 2009 17:36:07 -0700 Subject: ceph: warn on allocation from msgpool with larger front_len Pass the front_len we need when pulling a message off a msgpool, and WARN if it is greater than the pool's size. Then try to allocate a new message (to continue without failing).
