Package: nfs-common
Version: 1:1.3.4-6
Severity: important
Kernel: 5.10.0-16-amd64 #1 SMP Debian 5.10.127-1 (2022-06-30) x86_64 GNU/Linux
-- Description
After updating and or creating new files on our file server via rsync, we
see many files report the error message below from NFSv4 clients since
upgrading from Debian 10.8 to Debian 11.4.
Clearing the dentry cache resolves the issue right away.
I am not sure that nfs-common is the package to blame, but listed it based
on the bug submission recommendations.

ls -l /mnt/dir/someOtherDir/* | grep '?'
