Hi All, Just in case these issues have not been reported yet, I am on ubuntu 12.04, upgrade librados2/librados-dev from 0.48 to 0.56, and I notice the following issues: 1. librados2 / librados-dev still reports minor version as 48 Should minor version changed to 56? 2. In 0.48, rados_pool_list(cluster, NULL, 0) can be used like a buffer size query, and it would return the buffer size required for the pool list buffer string. In 0.56, this call now returns error -22 instead, and I have to pass in a tmp_buf[32] and len = 32 in order for the call to return successfully. I check the current rados_pool_list API, and it does not mention anything about buffer and len should not be NULL, 0. May be this was a bug in 0.48, that we should not pass in NULL, 0 ?
