From: "Valdis Klētnieks" <redacted> The staging/exfat driver has departed, but a lot of distros are still tracking 5.4-stable, so we should fix this. There was an 0/1 offset error in month handling for file metadata, causing the month to get incremented on each reference to the file. Thanks to Sebastian Gurtler for troubleshooting this, and Arpad Mueller for bringing it to my attention.
