From fc9f59de26afb3b4a33d37f1ba51a441b050afbb Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Thu, 31 Oct 2024 16:14:31 +0100 Subject: [PATCH] io_uring: Switch to use hrtimer_setup_on_stack() hrtimer_setup_on_stack() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init_on_stack() and the open coded initialization of hrtimer::function with the new setup mechanism.
