Linux 5.9 Quick Filesystem Test

Testing some workloads that are regressed by 2a9127fc during the Linux 5.9 merge window. Default mount options for all file-systems. Freshly formatted each time. Quick comparison by Michael Larabel looking at impact of file-system on this Linux 5.9 kernel regression.Tests running from the Micron 9300 SSD.
