Same note as the last time, not great that it's over the 15 patches, but I don't see a good way to shrink it considering that the original series [2] is 22 patches long, and I'll somehow need to pull it it into the io_uring tree after. Please let me know if there is a strong feeling about that, and/or what would the preferred way be. -- Pavel Begunkov
