I pushed out your patches (with a few small changes), and set the default stack size for the msgr threads to 1MB.

Let me me know if I missed anything important. sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
