Without looking too closely at the log you sent, you can expect URING
records without an associated SYSCALL record when the uring op is
being processed in the io-wq or sqpoll context. In the io-wq case the
processing is happening after the thread finished the syscall but
before the execution context returns to userspace and in the case of
sqpoll the processing is handled by a separate kernel thread with no
association to a process thread.
