Subject: [PATCH 03/22] [RESEND] kprobes: unify kprobes_exceptions_nofify() prototypes
Date: Wed, 8 Nov 2023 13:58:24 +0100 [thread overview]
Message-ID: <20231108125843.3806765-4-arnd@kernel.org> (raw)
In-Reply-To: <20231108125843.3806765-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Most architectures that support kprobes declare this function in their
own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:
kernel/kprobes.c:1865:12: error: no previous prototype for 'kprobe_exceptions_notify' [-Werror=missing-prototypes]
1865 | int __weak kprobe_exceptions_notify(struct notifier_block *self,
Move the prototype into linux/kprobes.h so it is visible to all
the definitions.
Acked-by: Masami Hiramatsu (Google) <mhiramat@kernel.org>
