From 5a4ccaf37ffece09ef33f1cfec67efa8ee56f967 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Tue, 6 Jan 2009 21:15:32 +0100 Subject: kprobes: check CONFIG_FREEZER instead of CONFIG_PM Check CONFIG_FREEZER instead of CONFIG_PM because kprobe booster depends on freeze_processes() and thaw_processes() when CONFIG_PREEMPT=y. This fixes a linkage error which occurs when CONFIG_PREEMPT=y, CONFIG_PM=y and CONFIG_FREEZER=n. Reported-by: Cheng Renquan Signed-off-by: Masami Hiramatsu Signed-off-by: Rafael J.
