byte ranges on slo/dlo objects broken in master
The ceph master branch contains code that rejects byte ranges on swift DLO / SLO objects.
File "dlo-byterange.txt" describes how to recreate the problem.
The problem appears to have been introduced by commit a94ec15a3b67795fed6008520eae0ca4f43f38b3
which is in response to http://tracker.ceph.com/issues/16388
This problem is only in master -not in jewel or hammer.
Reverting this commit restores correct behavior for this problem.
