io_uring: mark task TASK_RUNNING before handling resume/task work
stable inclusion from stable-v5.10.173 commit 3d1f9533a39d16f18ed7e630ecb07c0c2181b2cd category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8BFR3 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3d1f9533a39d16f18ed7e630ecb07c0c2181b2cd -------------------------------- commit 2f2bb1ff upstream. Just like for task_work, set the task mode to TASK_RUNNING before doing potential resume work. We're not holding any locks at this point, but we may have already set the task state to TASK_INTERRUPTIBLE in preparation for going to sleep waiting for events. Ensure that we set it back to TASK_RUNNING if we have work to process, to avoid warnings on calling blocking operations with !TASK_RUNNING.
