4    This macro defines the function to be called at module removal
5    time (or never, in the case of the file compiled into the
6    kernel).  It will only be called if the module usage count has
7    reached zero.  This function can also sleep, but cannot fail:
8    everything must be cleaned up by the time it returns.
9   </p><p>
10    Note that this macro is optional: if it is not present, your
11    module will not be removable (except for 'rmmod -f').
