-probe is called to verify the existence of a certain type of

+The probe() entry is called in task context, with the bus's rwsem locked

+container_of() to convert "dev" to a bus-specific type, both in probe()
+and other routines. That type often provides device resource data, such

+ * klist.c - Routines for manipulating klists.
+ *
+ *
+ * This klist interface provides a couple of structures that wrap around
+ * struct list_head to provide explicit list "head" (struct klist) and
+ * list "node" (struct klist_node) objects. For struct klist, a spinlock
+ * is included that protects access to the actual list itself. struct
+ * klist_node provides a pointer to the klist that owns it and a kref
+ * reference count that indicates the number of current users of that node
+ * in the list.
+ *
+ * The entire point is to provide an interface for iterating over a list
+ * that is safe and allows for modification of the list during the
+ * iteration (e.g. insertion and removal), including modification of the
+ * current node on the list.
+ *
+ * It works using a 3rd object type - struct klist_iter - that is declared
+ * and initialized before an iteration. klist_next() is used to acquire the
+ * next element in the list. It returns NULL if there are no more items.
+ * Internally, that routine takes the klist's lock, decrements the reference
+ * count of the previous klist_node and increments the count of the next
+ * klist_node. It then drops the lock and returns.
+ *
+ * There are primitives for adding and removing nodes to/from a klist.
+ * When deleting, klist_del() will simply decrement the reference count.
+ * Only when the count goes to 0 is the node removed from the list.
+ * klist_remove() will try to delete the node from the list and block
+ * until it is actually removed. This is useful for objects (like devices)
+ * that have been removed from the system and must be freed (but must wait
+ * until all accessors have finished).
