Bug Description
After upgrading from 20.04 to 20.10 yesterday, my backup overnight failed. rclone reported these errors trying to read from the CIFS filesystem being backed up:

In addition I see the following in dmesg:
[ 371.203517] CIFS: VFS: \\[private LAN host name elided]\photo Close interrupted close
[ 373.131953] CIFS: VFS: \\[private LAN host name elided]\photo Close interrupted close
[ 374.421419] CIFS: VFS: \\[private LAN host name elided]\photo Close interrupted close
I want to emphasize that this worked fine in 20.04 basically forever, and then stopped working immediately after upgrading to 20.10. I tried rebooting, didn't help.
