Hi Ceph, Here is a sorted list of authors and organizations who contributed to v0.83, by number of commits or reviews back to v0.82. The affiliation of authors to organizations can be updated by submitting a patch to https://github.com/ceph/ceph/blob/master/.organizationmap All commits are reviewed but the number of reviews is a fraction of the number of commits. More often than not, the reviewer(s) is only mentioned in the message of the merge although it means that all associated commits have been reviewed. If you are curious about how it is done, the details are at the end of this mail.
