raiden00pl 5a209a853e sched/wqueue: restore -ENOENT from work_cancel() for unqueued work ... work_cancel() used to return -ENOENT when the work structure was not in the queue, and callers depend on that: aio_cancel() tears down the AIO container (file_put() + aioc_free()) only when work_cancel() reports success, because a work item that is not queued may already be executing on a worker thread (see the comment in fs/aio/aio_cancel.c). Since commit 6f72f5481d ("sched/wqueue: Refactor delayed and periodical workqueue") work_cancel() returns OK unconditionally, and commit d2e01b9055 ("sched/wqueue: harden custom queue lifecycle") kept that behaviour and dropped -ENOENT from the function documentation. Under SMP the LTP aio_cancel tests then free the aio container and its file while the lpwork thread is still executing aio_write_worker() on it, which ends in a page fault in file_write() (f_inode == NULL) and a panic. Return -ENOENT again when the work is not queued, and document it. For the synchronous variant "not queued" alone does not tell whether the callback is running: the worker scan does, so report OK when a running callback was found and waited for, and -ENOENT only when the work was neither queued nor running.
