Hi
Thanks for the reply.
But i am really confused about the nfs superblock and root directory
maintainance.
For example
If we mount two partition as shown below
mount -t nfs host1:/export/dir1 /mnt/dir1/
mount -t nfs host2:/export/dir2 /mnt/dir2/
Then will there be two nfs superbocks created one per each mount?
If not and if there is only one nfs superblock then s_root entry of
the nfs superbolck will point to which root directory(of the first or
second mount).

The over the wire GETATTR function is used during mounting to get the
initial set of attributes for the root of the mounted file system.
From time to time, GETATTR is also used to validate the attributes and
cached resources associated with entities on the mounted file system.
