From ac42f636dc11b2e8d6dea9dd5bb10a39c7bec342 Mon Sep 17 00:00:00 2001 From: Daniel Xu Date: Wed, 12 Jun 2024 09:58:29 -0600 Subject: [PATCH] bpf: selftests: Fix bpf_map_sum_elem_count() kfunc prototype The prototype in progs/map_percpu_stats.c is not in line with how the actual kfuncs are defined in kernel/bpf/map_iter.c. This causes compilation errors when kfunc prototypes are generated from BTF. Fix by aligning with actual kfunc definitions.
