Hi Benjamin,

After merging the aio tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

fs/built-in.o: In function `aio_thread_op_foo_at':
file.c:(.text+0x43808): undefined reference to `__get_user_bad'
file.c:(.text+0x43838): undefined reference to `__get_user_bad'

Caused by commit

  150a0b4905f1 ("aio: add support for async openat()")  

How did that code end up in linux-next anyway?

Via the aio tree (git://git.kvack.org/~bcrl/aio-next.git#master) added
in July 2013 at Ben's request.  The code was added to the aio tree in
Jan 12 (my time), but has never been in a published linux-next tree due
to the above build problem (I back out to the previous days version of
the aio tree).
