- Implement the correct random write testing algorithm which is not
influenced by Bluestore's deferred writes coalescing into a single
operation: write 4Kb blocks in random positions of one of 16 4MB
objects per OSD, also chosen randomly
- Remove MB/sec from the statistical breakdown lines
- Use sync writes (basically the same, but code is simpler)
- Remove -DYA_PIDOR, always use urandom
- Build with tcmalloc
- Change curly brace style :-)
