This parameter controls whether SMB share modes are translated into file system specific sharemode calls. Kernel share modes provide a minimal level of interoperability with local UNIX processes and NFS operations by preventing access corresponding to the SMB share modes. This requires a file system specific VFS module with proper support. Note that in order to use SMB2 durable file handles on a share, you have to turn kernel share modes off. This parameter defaults to no. Setting it to yes requires a file system module that supports file system sharemodes, otherwise attempts to access files will fail with a sharing violation. no
