[Samba] Filelocking Issue in 4.18.11

[Stolte, Felix]

Hi Ralph,

thanks a lot. We are using the ceph filesystem as our backend. I checked the dev/inode of the same file on both nodes and in fact the dev number differed. It looks to me that the the dev number relates to the order in which the the filesystems are mounted during boot. 

We are using vfs_fileid now and the filelocking issue seems to be gone.
