From 444cb7db4c9f9b5d96be17c38b3e989df7bfabd5 Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Thu, 31 Oct 2024 16:14:21 +0100 Subject: hrtimers: Introduce hrtimer_setup_on_stack() To initialize hrtimer on stack, hrtimer_init_on_stack() needs to be called and also hrtimer::function must be set. This is error-prone and awkward to use. Introduce hrtimer_setup_on_stack() which does both of these things, so that users of hrtimer can be simplified. The new setup function also has a sanity check for the provided function pointer. If NULL, a warning is emitted and a dummy callback installed. hrtimer_init_on_stack() will be removed as soon as all of its users have been converted to the new function.
