From d52f847a841bfeba0ea87a7842732d388a1ca2e8 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 1 Apr 2010 15:23:14 -0700 Subject: ceph: rewrite msgpool using mempool_t Since we don't need to maintain large pools of messages, we can just use the standard mempool_t. We maintain a msgpool 'wrapper' because we need the mempool_t* in the alloc function, and mempool gives us only pool_data.
