[PATCHSET for-next 0/2] tctx setup cleanups

[Jens Axboe <axboe@kernel.dk>]

Hi,

It's a bit annoying how io_uring_alloc_task_context() automatically
assigns tsk->io_uring, when callers later may have paths that fail.
This is fine because task cleanup deals with whatever state that
->io_uring may be in, but it would be cleaner to have it either be
assigned if it's fully setup, or not assigned at all. These 2 patches
do that by having io_uring_alloc_task_context() return the context
rather than implicitly assigning it inside the task being passed. The
caller must instead assign it to the task, when any operation that can
fail has been completed.

No functional changes intended in this series, strictly a cleanup
