The reason is that this patch fixes a race condition in function async_completion() in drivers/nvme/host/pci.c . However, this function had been removed entirely in commit c33e9323c87556f335378113837cab4aab7d8a85 as part of http://bugs.launchpad.net/bugs/1531539
Therefore I believe that patch is no longer necessary for Xenial and so I skipped it.
