Hi Loic, It's not strange that you worry about that since we have committed lots of pull requests into the main trunk so far. However, we are considering each pull request already committed was either a bug fix or a performance improvement, so we believe we are qualified to backport them into hammer. Anyway, we tried to backport it on our local repository in order to decide whether it's feasible or not and felt that it's not so difficult although we had to resolve a little complicated conflicts. In addition, we could have selected only local commits in shec directory and avoided changing any erasure code I/F. Here is the result of our backport trial. https://github.com/t-miyamae/ceph/commits/hammer We are very glad if you could check it out and let us know your opinion after that. We are testing it on our cluster for a couple of days in parallel.

Hi, Since SHEC really is a new feature in Infernalis (because it was experimental before), I'll leave it to Sam and Sage to decide if it's relevant to backport to Hammer. Note that it depends on changes in the erasure code base that extend to all plugins. Backporting would unfortunately not be as simple as cherry-picking the commits modifying the shec directories.
