Item 5 of the cover letter reply: drop the table and the "~24% of all
cpus" from the message and post them in this thread. Say instead what
gets faster: io_uring no longer punts every request to io-wq.

Why: the numbers hold only on the box and the job they were measured
with, a later reader of the commit cannot act on them.

The code is correct. Alexander's request to put this patch after the
batching one still needs an answer (item 7).
