This patch removes the duplicate initialization of q->queue_head
in the blk_alloc_queue_node(). This removes the 2nd initialization
so that we preserve the initialization order same as declaration
present in struct request_queue.

Hi Hannes,
Thanks for the test, this is really helpful, please see my inline comments to
individual patches.
Also, the test number should be I guess 18, 14-17 testcases are still in the
queue.
Omar, can you please let us know when can you merge the remaining testcases for
NVMeOF
from the
This is a cleanup patch which uses consistent return values
for helper functions.

Add support for handling write zeroes command on target.
Call into __blkdev_issue_zeroout, which the block layer expands into the
best suitable variant of zeroing the LBAs. Allow write zeroes operation
to deallocate the LBAs when calling __blkdev_issue_zeroout.

From: Chaitanya Kulkarni <chaitanya.kulka...@hgst.com>
This adds a new block layer operation to zero out a range of
LBAs. This allows to implement zeroing for devices that don't use
either discard with a predictable zero pattern or WRITE SAME of zeroes.
The prominent example of that i
1. Block layer implementation details :-
a. Introducing __blkdev_issue_zeroout variant of exiting code.
b. Introducing new request operation flag REQ_OP_WRITE_ZEROES to represent
write zeroes operation.
c. Mechanism to issue bios without payload with the help of

Similar to __blkdev_issue_discard this variant allows submitting
the final bio asynchronously and chaining multiple ranges
into a single completion.
