Merge tag 'for-6.3/iter-ubuf-2023-02-16' of git://git.kernel.dk/linux
Pull io_uring ITER_UBUF conversion from Jens Axboe:
"Since we now have ITER_UBUF available, switch to using it for single
ranges as it's more efficient than ITER_IOVEC for that"
* tag 'for-6.3/iter-ubuf-2023-02-16' of git://git.kernel.dk/linux:
block: use iter_ubuf for single range
iov_iter: move iter_ubuf check inside restore WARN
io_uring: use iter_ubuf for single range imports
io_uring: switch network send/recv to ITER_UBUF
iov: add import_ubuf()
