9P2010.L handshake: Add VFS flags
Add 9P2000.u and 9P2010.L protocol flags to V9FS VFS This patch adds 9P2000.u and 9P2010.L protocol flags into V9FS VFS side code and removes the single flag used for 'extended'. Signed-off-by: Sripathi Kodi <sripathik@in.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
