After merging of this pull request into linus-next, I've started seeing
build errors:

/builds/linux/io_uring/rw.c: In function 'io_hybrid_iopoll_delay':
/builds/linux/io_uring/rw.c:1179:2: error: implicit declaration of function 'hrtimer_init_sleeper_on_stack'; did you mean 'hrtimer_setup_sleeper_on_stack'? [-Werror=implicit-function-declaration]
   hrtimer_init_sleeper_on_stack(&timer, CLOCK_MONOTONIC, mode);
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
   hrtimer_setup_sleeper_on_stack

This is because 01ee194d1aba ("io_uring: add support for hybrid IOPOLL")
adds a call to hrtimer_init_sleeper_on_stack() which was removed earlier
today in Thomas's PR[1], specifically in commit f3bef7aaa6c8
("hrtimers: Delete hrtimer_init_sleeper_on_stack()").
