Hi all,

After merging the block tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/io_uring.c: In function 'io_resubmit_prep':
fs/io_uring.c:2357:10: error: 'struct io_kiocb' has no member named 'io'
 2357 |  if (!req->io) {
      |          ^~

Caused by commit

  8f3d749685e4 ("io_uring: don't re-setup vecs/iter in io_resumit_prep() is already there")

from Linus' tree interacting with commit

  76c917267129 ("io_uring: get rid of req->io/io_async_ctx union")

from the block tree.

I added the following merge resolution:
