Apologies for the late reply. I can certainly test on some of my VMs if you're willing to provide packages. Reading over Linus' explanation of deriving jitter from the CPU's cycle counter, while I'm no cryptographer, I might have some concerns about the quality of the entropy that will be generated by this patch on hypervisors that virtualize the time stamp counter. In my environment, I know I can instruct Xen to never virtualize the TSC ( https://xenbits.xen.org/docs/unstable/man/xen-tscmode.7.html), which would probably benefit the patch, but AWS and other public cloud users may not have that option. -Michael
