namlen is not a valid option for NFSv4. Currently, we could pass a namlen=xxx in a NFSv4 mount, the mount command succeed and namlen is ignored silently # mount -o vers=4,namlen=100 192.168.122.19:/nfsroot /mnt/ -vvv mount.nfs: timeout set for Fri Mar 22 14:22:18 2024 mount.nfs: trying text-based options 'namlen=100,vers=4.2, addr=192.168.122.19,clientaddr=192.168.122.15' This patch will remove "namlen=" option in a NFSv4 mount, and give a warning message in verbose mode.
