Hi Jens,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/nvme/host/scsi.c: In function 'nvme_scsi_translate':
drivers/nvme/host/scsi.c:2350:9: error: 'BLK_MAX_CDB' undeclared (first use in this function)
u8 cmd[BLK_MAX_CDB];
drivers/nvme/host/scsi.c:2350:9: note: each undeclared identifier is reported only once for each function it appears in
drivers/nvme/host/scsi.c:2350:5: warning: unused variable 'cmd' [-Wunused-variable]
u8 cmd[BLK_MAX_CDB];
drivers/nvme/host/scsi.c: In function 'nvme_sg_io':
drivers/nvme/host/scsi.c:2454:20: error: 'BLK_MAX_CDB' undeclared (first use in this function)
if (hdr.cmd_len > BLK_MAX_CDB)

Caused by commit

82ed4db499b8 ("block: split scsi_request out of struct request")

I have used the block tree from next-20170125 for today.
