Subject: [PATCH v2 0/3] io_uring: Pass the whole sqe to commands
Date:   Fri, 21 Apr 2023 04:44:37 -0700

These three patches prepare for the sock support in the io_uring cmd, as
described in the following RFC:

	https://lore.kernel.org/lkml/20230406144330.1932798-1-leitao@debian.org/

Since the support linked above depends on other refactors, such as the sock
ioctl() sock refactor[1], I would like to start integrating patches that have
consensus and can bring value right now.  This will also reduce the patchset
size later.

Regarding to these three patches, they are simple changes that turn
io_uring cmd subsystem more flexible (by passing the whole SQE to the
command), and cleaning up an unnecessary compile check.

These patches were tested by creating a file system and mounting an NVME disk
using ubdsrv/ublkb0.
