[LU-12514] separate out the lustre mount code for server and clients

• Type: Improvement
• Resolution: Unresolved
• Priority: Minor
• Assignee: James A Simmons
• Reporter: James A Simmons

Description

During LUG it was discussed how Lustre uses the same file system type for both servers and clients. This is something the kernel VFS maintainer would rather see handled differently. This ticket tracks the changes upstream for the client as well as implement the needed server side changes.
