+
+ <para>Samba uses file_id structs to uniquely identify files
+ for locking purpose. By default the file_id contains the device
+ and inode number returned by the <command>stat()</command> system call.
+ As the file_id is a unique identifier of a file, it must be the same
+ on all nodes in a cluster setup. This module overloads the
+ <command>SMB_VFS_FILE_ID_CREATE()</command> operation and
+ generates the device number based on the configured algorithm
+ (see the "fileid:algorithm" option).
