Comment 37 for bug 2007055

Thanks for sharing that. Your cifs-utils is the same that I have on an ubuntu 22 VM, which shows the issue with a server running an earlier version of Samba (4.7.x) and a later version. I unfortunately don't readily have a VM with 4.8.x readily available, but the brittleness of file modtime preservation depending on client and server is surprising, and I can understand the sarcastic comment! :-)
