Here's v2 of the linked SQE patchset. For a full description of this
feature, please refer to the v1 posting:

https://lore.kernel.org/linux-block/20190517214131.5925-1-axboe@kernel.dk/

Changes since v1 are just fixes, and nothing major at that. Some of the
v1 error handling wasn't quite correct, this should be. The liburing
repo contains the link-cp copy implementation using linked SQEs, and
also has a test case that exercises a few of the link combinations.

Patches are against my for-linus branch, but should apply to Linus
master just fine as well.
