I tested the change on Azure using Standard L8s_v2 (8 vcpus, 64 GiB memory) VMs using the 5.4 linux-azure kernel on bionic and the 5.8 kernel on groovy.
During my tests the VMs continued to successfully hibernate with the patch and the time needed to save the VM state went down from 25 seconds to around 3 seconds.
