Hi,

This patch-series is based on the initial patch posted by 
Christoph Hellwig <hch@lst.de>. I've added one more patch to improve
further print message.

While debugging the driver and block layer this print message is very
handy.

Please consider this for 5.3.

Following is the sample error message with forced REQ_OP_WRITE failure
from null_blk:-

blk_update_request: I/O error, dev nullb0, sector 0 op 0x1:(write) flags 0x8800 phys_seg 1 prio class 0
