Hi Ceph,
Here is a sorted list of authors and organizations who contributed to v0.77, by
number of commits or reviews back to v0.76. 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.
Thanks Loic! Great to see so many people contributing to Ceph! I never
figured it were so many people from different organizations.
Very valuable information!
Wido

Authors names are normalized with .mailmap and authors affiliations to a given
organization comes from .organizationmap, both of which can be found and
patched at the root of the ceph source tree.
More sophisticated reports can be generated and visualized by tools such as
http://bitergia.com/ or http://stackalytics.com/. Cheers
