Hi Philipp,
Today's linux-next build (x86_64 allmodconfig) failed like this:
drivers/block/drbd/drbd_req.c: In function 'drbd_make_request_26':
drivers/block/drbd/drbd_req.c:1023: error: implicit declaration of function 'bio_barrier'
drivers/block/drbd/drbd_actlog.c: In function '_drbd_md_sync_page_io':
drivers/block/drbd/drbd_actlog.c:120: error: implicit declaration of function 'bio_barrier'
drivers/block/drbd/drbd_main.c: In function 'drbd_send_dblock':
drivers/block/drbd/drbd_main.c:2373: error: implicit declaration of function 'bio_barrier'
drivers/block/drbd/drbd_main.c:2375: error: implicit declaration of function 'bio_sync'
Caused by commit d206aaff0c5ee065f382c626ea21c5166a3047a7 ("bio: first
step in sanitizing the bio->bi_rw flag testing") from the block tree.
I applied the following patch for today.
