From 05ed160e89baf7f5fb3432d527fec467d2493626 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Mon, 13 Sep 2010 19:25:41 +0900 Subject: [PATCH] kprobes: Fix Kconfig dependency Fix Kconfig dependency among Kprobes, optprobe and kallsyms. Kprobes uses kallsyms_lookup for finding target function and checking instruction boundary, thus CONFIG_KPROBES should select CONFIG_KALLSYMS. Optprobe is an optional feature which is supported on x86 arch, and it also uses kallsyms_lookup for checking instructions in the target function. Since KALLSYMS_ALL just adds symbols of kernel variables, it doesn't need to select KALLSYMS_ALL.
