Do a diff: it shows
- struct {
- caddr_t b_addr; /* Memory, superblocks, indirect etc. */
- } b_un;
+ caddr_t b_data; /* Memory, superblocks, indirect etc. */
In other words, b_data is your friend. Previously it was defined like
this:
-/* Device driver compatibility definitions. */
-#define b_data b_un.b_addr /* b_un.b_addr is not changeable. */
Can you send me more details of the driver (offline if necessary)?
