Subject: [ 02/68] Fix autofs compile without CONFIG_COMPAT
Date: Fri, 09 Mar 2012 11:02:16 -0800 [thread overview]
Message-ID: <20120309190215.179442456@linuxfoundation.org> (raw)
In-Reply-To: <20120309194409.GA2069@kroah.com>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds <torvalds@linux-foundation.org>
commit 3c761ea05a8900a907f32b628611873f6bef24b2 upstream.
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.
