Optimize NFS open() calls by means of 'intents'...
- Add open intent information to the 'struct nameidata'.
- Pass the struct nameidata as an optional parameter to the
lookup() inode operation.
- Pass the struct nameidata as an optional parameter to the
d_revalidate() dentry operation.
- Make link_path_walk() set the LOOKUP_CONTINUE flag in nd->flags instead
of passing it as an extra parameter to d_revalidate().
- Make open_namei(), and sys_uselib() set the open()/create() intent
data.
