From e597c2984c64609c6e1e1ac803f00f7550705860 Mon Sep 17 00:00:00 2001 From: Anil S Keshavamurthy Date: Mon, 9 Jan 2006 20:52:45 -0800 Subject: [PATCH] kprobes: arch_remove_kprobe Currently arch_remove_kprobes() is only implemented/required for x86_64 and powerpc. All other architecture like IA64, i386 and sparc64 implementes a dummy function which is being called from arch independent kprobes.c file. This patch removes the dummy functions and replaces it with #define arch_remove_kprobe(p, s) do { } while(0) Signed-off-by: Anil S Keshavamurthy Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/x86_64/kernel/kprobes.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'arch/x86_64') diff --git a/arch/x86_64/kernel/kprobes.c b/arch/x86_64/kernel/kprobes.c index 128e18190f9..61a6a9369cb 100644 --- a/arch/x86_64/kernel/kprobes.c +++ b/arch/x86_64/kernel/kprobes.c @@ -220,9 +220,11 @@ void __kprobes arch_disarm_kprobe(struct kprobe *p) (unsigned long) p->addr + sizeof(kprobe_opcode_t)); } -void __kprobes arch_remove_kprobe(struct kprobe *p) +void __kprobes arch_remove_kprobe(struct kprobe *p, struct semaphore *s) { + down(s); free_insn_slot(p->ainsn.insn); + up(s); } static inline void save_previous_kprobe(struct kprobe_ctlblk *kcb) -- cgit v1.2.2
