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@xxxxxxxxxx/ 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.
