From b8cff7d0320e3b39f098d9562373e1c16c54c46c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 25 Aug 2022 16:17:57 +0200 Subject: [PATCH 07/62] bpf: Remove the obsolte u64_stats_fetch_*_irq() users. Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.1/older/patches-6.1.69-rt21.tar.xz Now that the 32bit UP oddity is gone and 32bit uses always a sequence count, there is no need for the fetch_irq() variants anymore. Convert to the regular interface.
