60 *	Slot states for PIOCGSTATE
61 *
62 *	Here's a state diagram of all the possible states:
63 *
64 *                             power x 1
65 *                       -------------------
66 *                      /                   \
67 *                     /                     v
68 *    resume    +----------+   power x 0   +----------+
69 *      ------->| inactive |<--------------| filled   |
70 *     /        +----------+               +----------+
71 *    /           /     \                   ^   |
72 *  nil <---------       \        insert or |   | suspend or
73 *        suspend         \       power x 1 |   | eject
74 *                         \                |   v
75 *                          \            +----------+
76 *                           ----------->|  empty   |
77 *                             eject     +----------+
78 *
79 *	Note, the above diagram is for the state.  On suspend, the laststate
80 * gets set to suspend to tell pccardd what happened.  Also the nil state
81 * means that when the no state change has happened.  Note: if you eject
82 * while suspended in the inactive state, you will return to the
83 * empty state if you do not insert a new card and to the inactive state
84 * if you do insert a new card.
85 *
86 * Some might argue that inactive should be sticky forever and
87 * eject/insert shouldn't take it out of that state.  They might be
88 * right.  On the other hand, some would argue that eject resets all
89 * state.  They might be right.  They both can't be right.  The above
90 * represents a reasonable compromise between the two.
91 *
92 * Some bridges allow one to query to see if the card was changed while
93 * we were suspended.  Others do not.  We make no use of this functionality
94 * at this time.
