Well after a short cross over look at it I agree.
The generic interface looks sane for me as well. However
I will have to look a bit deeper, becouse at the first sight
the double pointer to tag_index looks a bit "overelaborate"
to me. But I may change my opinnion after looking at the
actual usage - so please take this small bit of critique
with a good grain of salt...
+#define BLK_TAGS_PER_LONG (sizeof(unsigned long) * 8)
+#define BLK_TAGS_MASK (BLK_TAGS_PER_LONG - 1)
+
+struct blk_queue_tag {
+
struct request **tag_index; /* map of busy tags */
+
unsigned long *tag_map; /* bit map of free/busy tags */
+
struct list_head busy_list; /* fifo list of busy tags */
+
int busy; /* current depth */
+
int max_depth;
+};
