Subject: [PATCH] inherit clone nfs_sever's rsize and wsize from parent


I think this is a minor issue.

When a mount is cloned, the new nfs_server's rsize and wsize do not
inherit their initial values from the parent mount.
nfs_server_set_fsinfo() ends up setting the new nfs_server's rsize and
wsize to the values returned in the FSINFO response. As a result,
there is no way for a system administrator to configure the rsize and
wsize of a cloned mount.

The patch below makes the cloned nfs_server inherit its initial rsize
and wsize from its parent.
