is related to LU-28 Ability for client to mount subdirect... Resolved
Rank (Obsolete): 16706

 Description   

We might need subdirectory export for Lustre, just like NFS, we could use
it from clients something like this:

mount -t lustre xxxxx -o subdir="/test_dir" <mnt>

Actually, we could implement it using a recursive way, we filter out mount options so that second mount will stop.
