Hi, I suspect there is a corner case for io_uring in release 5.8. Can you please explain where the associated mmdrop/kthread_unuse_mm calls for io_sq_thread_acquire_mm in io_init_req(...) are? Specifically, what would happen if there was an error after calling io_sq_thread_acquire_mm (for example, the -EINVAL a few lines after)? >From what I can understand, it looks like the kthread_unuse_mm and mmput might be handled in the call to io_sq_thread_acquire_mm in io_sq_thread. However, I am not seeing where mmdrop might be called. Thanks, Ryan
