+ * Due to frequent changes in the shrinker API the following
|
|
+ * compatibility wrappers should be used. They are as follows:
|
|
+ *
|
|
+ * SPL_SHRINKER_DECLARE is used to declare the shrinker which is
|
|
+ * passed to spl_register_shrinker()/spl_unregister_shrinker(). Use
|
|
+ * shrinker_name to set the shrinker variable name, shrinker_callback
|
|
+ * to set the callback function, and seek_cost to define the cost of
|
|
+ * reclaiming an object.
|
|
+ *
|
|
+ * SPL_SHRINKER_DECLARE(shrinker_name, shrinker_callback, seek_cost);
|
|
+ *
|
|
+ * SPL_SHRINKER_CALLBACK_FWD_DECLARE is used when a forward declaration
|
|
+ * of the shrinker callback function is required. Only the callback
|
|
+ * function needs to be passed.
|
|
+ *
|
|
+ * SPL_SHRINKER_CALLBACK_FWD_DECLARE(shrinker_callback);
|
|
+ *
|
|
+ * SPL_SHRINKER_CALLBACK_WRAPPER is used to declare the callback function
|
|
+ * which is registered with the shrinker. This function will call your
|
|
+ * custom shrinker which must use the following prototype. Notice the
|
|
+ * leading __'s, these must be appended to the callback_function name.
|
|
+ *
|
|
+ * int __shrinker_callback(struct shrinker *, struct shrink_control *)
|
|
+ * SPL_SHRINKER_CALLBACK_WRAPPER(shrinker_callback);a
|
|
+ *
|
|
+ *
|
|
+ * Example:
|
|
+ *
|

+ * SPL_SHRINKER_CALLBACK_FWD_DECLARE(my_shrinker_fn);
|
|
+ * SPL_SHRINKER_DECLARE(my_shrinker, my_shrinker_fn, 1);
