Subject: stec skd block driver needs updating for immutable biovec

Hey Jens and Kent,

You're likely already aware of this but building the latest
linux-block.git 'for-next' I get:

  CC [M]  drivers/block/skd_main.o
drivers/block/skd_main.c: In function ‘skd_request_fn’:
drivers/block/skd_main.c:773: error: ‘struct bio’ has no member named ‘bi_sector’
drivers/block/skd_main.c: In function ‘skd_end_request_bio’:
drivers/block/skd_main.c:1142: error: ‘struct bio’ has no member named ‘bi_sector’
drivers/block/skd_main.c: In function ‘skd_preop_sg_list_bio’:
drivers/block/skd_main.c:1198: error: implicit declaration of function ‘bio_iovec_idx’
drivers/block/skd_main.c:1198: warning: assignment makes pointer from integer without a cast
drivers/block/skd_main.c: In function ‘skd_log_skreq’:
drivers/block/skd_main.c:5814: error: ‘struct bio’ has no member named ‘bi_sector’
make[2]: *** [drivers/block/skd_main.o] Error 1
make[1]: *** [drivers/block] Error 2
make: *** [drivers] Error 2

All the bi_sector ones are low hanging fruit, but the conversion for
skd_preop_sg_list_bio()'s bio_vec code is more involved.

Kent, any chance you could crank through it?

If not I can come back to trying to fix this later.. but I'm working
through a test merge of linux-dm.git's 'for-next' with linux-block.git's
'for-next'.

(I happen to have one of these stec cards so I'll be able to test)

Mike
