ceph: rewrite msgpool using mempool_t2010-05-17T22:25:18ZSage Weilsage@newdream.net2010-04-01T22:23:14Zurn:sha1:d52f847a841bfeba0ea87a7842732d388a1ca2e8
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.

ceph: warn on allocation from msgpool with larger front_len2009-10-16T01:14:43ZSage Weilsage@newdream.net2009-10-15T00:36:07Zurn:sha1:8f3bc053c610826a657714649ea596f07875db2e
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).

ceph: message pools2009-10-06T18:31:13ZSage Weilsage@newdream.net2009-10-06T18:31:13Zurn:sha1:8fc91fd85950d106883852c6d215614ec28cc92d
The msgpool is a basic mempool_t-like structure to preallocate
messages we expect to receive over the wire. This ensures we have the
necessary memory preallocated to process replies to requests, or to
process unsolicited messages from various servers.
