Pull io_uring fixes from Jens Axboe: "A bit of a mix between fallout from the worker change, cleanups and reductions now possible from that change, and fixes in general. In detail: - Fully serialize manager and worker creation, fixing races due to that. - Clean up some naming that had gone stale. - SQPOLL fixes. - Fix race condition around task_work rework that went into this merge window. - Implement unshare. Used for when the original task does unshare(2) or setuid/seteuid and friends, drops the original workers and forks new ones. - Drop the only remaining piece of state shuffling we had left, which was cred. Move it into issue instead, and we can drop all of that code too. - Kill f_op->flush() usage. That was such a nasty hack that we had out of necessity, we no longer need it. - Following from ->flush() removal, we can also drop various bits of ctx state related to SQPOLL and cancelations. - Fix an issue with IOPOLL retry, which originally was fallout from a filemap change (removing iov_iter_revert()), but uncovered an issue with iovec re-import too late. - Fix an issue with system suspend. - Use xchg() for fallback work, instead of cmpxchg(). - Properly destroy io-wq on exec. - Add create_io_thread() core helper, and use that in io-wq and io_uring. This allows us to remove various silly completion events related to thread setup. - A few error handling fixes. This should be the grunt of fixes necessary for the new workers, next week should be quieter. We've got a pending series from Pavel on cancelations, and how tasks and rings are indexed. Outside of that, should just be minor fixes.

Pull NVMe fixes from Christoph: "nvme fixes for 5.12: - more device quirks (Julian Einwag, Zoltán Böszörményi, Pascal Terjan) - fix a hwmon error return (Daniel Wagner) - fix the keep alive timeout initialization (Martin George) - ensure the model_number can't be changed on a used subsystem (Max Gurtovoy)" * tag 'nvme-5.12-2021-03-05' of git://git.infradead.org/nvme: nvmet: model_number must be immutable once set nvme-fabrics: fix kato initialization nvme-hwmon: Return error code when registration fails nvme-pci: add quirks for Lexar 256GB SSD nvme-pci: mark Kingston SKC2000 as not supporting the deepest power state nvme-pci: mark Seagate Nytro XM1440 as QUIRK_NO_NS_DESC_LIST.
2021-03-05io_uring: make SQPOLL thread parking sanerJens Axboe1-35/+30
We have this weird true/false return from parking, and then some of the callers decide to look at that. It can lead to unbalanced parks and sqd locking. Have the callers check the thread status once it's parked. We know we have the lock at that point, so it's either valid or it's NULL. Fix race with parking on thread exit. We need to be careful here with ordering of the sdq->lock and the IO_SQ_THREAD_SHOULD_PARK bit. Rename sqd->completion to sqd->parked to reflect that this is the only thing this completion event doesn. Signed-off-by: Jens Axboe <[email protected]>
2021-03-05io-wq: kill hashed waitqueue before manager exitsJens Axboe1-4/+5
If we race with shutting down the io-wq context and someone queueing a hashed entry, then we can exit the manager with it armed. If it then triggers after the manager has exited, we can have a use-after-free where io_wqe_hash_wake() attempts to wake a now gone manager process. Move the killing of the hashed write queue into the manager itself, so that we know we've killed it before the task exits.

2021-03-05io_uring: clear IOCB_WAITQ for non -EIOCBQUEUED returnJens Axboe1-0/+1
The callback can only be armed, if we get -EIOCBQUEUED returned. It's important that we clear the WAITQ bit for other cases, otherwise we can queue for async retry and filemap will assume that we're armed and return -EAGAIN instead of just blocking for the IO.

2021-03-05io_uring: don't keep looping for more events if we can't flush overflowJens Axboe1-3/+12
It doesn't make sense to wait for more events to come in, if we can't even flush the overflow we already have to the ring. Return -EBUSY for that condition, just like we do for attempts to submit with overflow pending. Cc: [email protected] # 5.11 Signed-off-by: Jens Axboe <[email protected]>
2021-03-05io_uring: move to using create_io_thread()Jens Axboe3-109/+54
This allows us to do task creation and setup without needing to use completions to try and synchronize with the starting thread. Get rid of the old io_wq_fork_thread() wrapper, and the 'wq' and 'worker' startup completion events - we can now do setup before the task is running. Signed-off-by: Jens Axboe <[email protected]>
