From 68d3de7fc49c326205811a23d0a146feed0d4fee Mon Sep 17 00:00:00 2001 From: Nam Cao Date: Wed, 5 Feb 2025 11:39:14 +0100 Subject: [PATCH] null_blk: Switch to use hrtimer_setup() hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism. Patch was created by using Coccinelle.
