Btrfs RAID 0/1 Benchmarks On The Linux 4.1 Kernel

With the Linux 4.1 kernel coming together nicely I've begun my testing (separate from all the fully-automated Git testing done each day via the LinuxBenchmarking.com systems) of this new kernel under a variety of different workloads, stressing different systems, and focusing on the changes in the major subsystems. One of the systems this week has been running some fresh Btrfs RAID Linux file-system benchmarks. From an eight-disk server I've started this Btrfs RAID testing as some fresh numbers since my Btrfs RAID tests from a few months back on an older server.
