From 4c8c3c7f70a6779d30f5492acbc9978f4636fe7a Mon Sep 17 00:00:00 2001 From: Valentin Schneider Date: Tue, 7 Mar 2023 14:35:56 +0000 Subject: treewide: Trace IPIs sent via smp_send_reschedule() To be able to trace invocations of smp_send_reschedule(), rename the arch-specific definitions of it to arch_smp_send_reschedule() and wrap it into an smp_send_reschedule() that contains a tracepoint. Changes to include the declaration of the tracepoint were driven by the following coccinelle script: @func_use@ @@ smp_send_reschedule(...); @include@ @@ #include @no_include depends on func_use && !include@ @@ #include <...> + + #include [csky bits] [riscv bits] Signed-off-by: Valentin Schneider Signed-off-by: Peter Zijlstra (Intel) Acked-by: Guo Ren Acked-by: Palmer Dabbelt Link: https://lore.kernel.org/r/20230307143558.294354-6-vschneid@redhat.com --- arch/mips/include/asm/smp.h | 2 +- arch/mips/kernel/rtlx-cmp.c | 2 ++ 2 files changed, 3 insertions(+), 1 deletion(-) (limited to 'arch/mips') diff --git a/arch/mips/include/asm/smp.h b/arch/mips/include/asm/smp.h index 5d9ff61004ca..9806e79895d9 100644 --- a/arch/mips/include/asm/smp.h +++ b/arch/mips/include/asm/smp.h @@ -66,7 +66,7 @@ extern void calculate_cpu_foreign_map(void); * it goes straight through and wastes no time serializing * anything.
