From 3c761ea05a8900a907f32b628611873f6bef24b2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 26 Feb 2012 09:44:55 -0800 Subject: [PATCH] Fix autofs compile without CONFIG_COMPAT The autofs compat handling fix caused a compile failure when CONFIG_COMPAT isn't defined. Instead of adding random #ifdef'fery in autofs, let's just make the compat helpers earlier to use: without CONFIG_COMPAT, is_compat_task() just hardcodes to zero. We could probably do something similar for a number of other cases where we have #ifdef's in code, but this is the low-hanging fruit.
