Hi all,

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

io_uring/rw.c: In function 'io_hybrid_iopoll_delay':
io_uring/rw.c:1179:9: error: implicit declaration of function 'hrtimer_init_sleeper_on_stack'; did you mean 'hrtimer_setup_sleeper_on_stack'? [-Wimplicit-function-declaration]
 1179 |         hrtimer_init_sleeper_on_stack(&timer, CLOCK_MONOTONIC, mode);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |         hrtimer_setup_sleeper_on_stack

Caused by commit

  f3bef7aaa6c8 ("hrtimers: Delete hrtimer_init_sleeper_on_stack()")

interacting with commit

  01ee194d1aba ("io_uring: add support for hybrid IOPOLL")

from the block tree.

I have applied the following merge fix patch.
