From b3b3a9b63f2deacfd59137e3781211d21a568ca9 Mon Sep 17 00:00:00 2001 From: Anand Gadiyar Date: Thu, 14 Oct 2010 11:31:42 -0400 Subject: [PATCH] oprofile: fix linker errors Commit e9677b3ce (oprofile, ARM: Use oprofile_arch_exit() to cleanup on failure) caused oprofile_perf_exit to be called in the cleanup path of oprofile_perf_init. The __exit tag for oprofile_perf_exit should therefore be dropped. The same has to be done for exit_driverfs as well, as this function is called from oprofile_perf_exit. Else, we get the following two linker errors. LD .tmp_vmlinux1 `oprofile_perf_exit' referenced in section `.init.text' of arch/arm/oprofile/built-in.o: defined in discarded section `.exit.text' of arch/arm/oprofile/built-in.o make: *** [.tmp_vmlinux1] Error 1 LD .tmp_vmlinux1 `exit_driverfs' referenced in section `.text' of arch/arm/oprofile/built-in.o: defined in discarded section `.exit.text' of arch/arm/oprofile/built-in.o make: *** [.tmp_vmlinux1] Error 1 Signed-off-by: Anand Gadiyar Cc: Will Deacon Signed-off-by: Robert Richter --- drivers/oprofile/oprofile_perf.c | 2 +- include/linux/oprofile.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/oprofile/oprofile_perf.c b/drivers/oprofile/oprofile_perf.c index e707a72a3799..36ec67e3d91d 100644 --- a/drivers/oprofile/oprofile_perf.c +++ b/drivers/oprofile/oprofile_perf.c @@ -236,7 +236,7 @@ static int __init init_driverfs(void) return ret; } -static void __exit exit_driverfs(void) +static void exit_driverfs(void) { platform_device_unregister(oprofile_pdev); platform_driver_unregister(&oprofile_driver); diff --git a/include/linux/oprofile.h b/include/linux/oprofile.h index d67a8330b41e..32fb81212fd1 100644 --- a/include/linux/oprofile.h +++ b/include/linux/oprofile.h @@ -188,7 +188,7 @@ int oprofile_write_commit(struct op_entry *entry); #ifdef CONFIG_PERF_EVENTS int __init oprofile_perf_init(struct oprofile_operations *ops); -void __exit oprofile_perf_exit(void); +void oprofile_perf_exit(void); char *op_name_from_perf_id(void); #endif /* CONFIG_PERF_EVENTS */ -- 2.20.1
