This series looks good to me now, but will need some slight rebasing since the 5.20 io_uring branch has split up the code a bit. Trivial to do though, I suspect it'll apply directly if we just change fs/io_uring.c to io_uring/rw.c instead. The bigger question is how to stage this, as it's touching a bit of fs, mm, and io_uring... -- Jens Axboe
