In general we try very hard to avoid them, but if eg we get a short read
or write from blocking context (eg io-wq), then io_uring does return
that. There's really not much we can do here, it seems futile to retry
IO which was issued just like it would've been from a normal blocking
syscall yet it is still short.

I ran into this issue and tested the patch. Works for me!
