See linux-2.6/Documentation/filesystems/proc.txt for details:

shared:X  mount is shared in peer group X
master:X  mount is slave to peer group X
propagate_from:X  mount is slave and receives propagation from peer group X (*)
unbindable  mount is unbindable

linux-2.6/Documentation/filesystems/sharedsubtree.txt also has good info
(as does fs/namespace.c).
