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_sq_thread':
fs/io_uring.c:6787:3: error: implicit declaration of function 'io_ctx_disable_sqo_submit' [-Werror=implicit-function-declaration]
 6787 |   io_ctx_disable_sqo_submit(ctx);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  a6afa091d06a ("io_uring: move SQPOLL thread io-wq forked worker")

I have used the block tree from next-20210222 for today.
