Description

We just fixed ceph_test_rados to wait for commit, not ack. It turns out that the RWORDERED flag is ordering a

write1, write2, read

properly with the acks, but not commits. That is, you get

write1 ack, write2 ack, read, write1 commit, write2 commit

This makes ceph_test_rados crash and burn when backed by btrfs. For writeahead journaling it doesn't notice the difference.
