I was adding tests for clone_range in preparation for improving the bluestore implementation and got stuck on memstore and filestore bugs! The most alarming is that filestore very quickly fails the tests if filestore_fiemap is enabled. It's off by default (phew!) but the ceph_test_objectstore test was explicitly enabling it to get better coverage. For now I've just removed that so we stick with the default (no fiemap == good). I wonder if we should consider removing fiemap from the code entirely, though, since it is clearly buggy, even on a modern kernel (I'm running 4.4 and XFS). I also hit bugs in memstore. I fixed the one in the BufferlistObject implementation, but the PageSet one I couldn't figure out after 20 minutes, so I changed the default config to memstore_page_set = false for now. Perhaps Casey or Adam or whoever wrote that can take a look? It's very easy to reproduce.
