Hi Benjamin, After merging the aio tree, today's linux-next build (powerpc ppc64_defconfig) failed like this:
fs/aio.c: In function 'aio_kernel_init_rw':
fs/aio.c:1359:6: error: 'struct kiocb' has no member named 'ki_left'

Caused by commit af9fa2024c38 ("aio: add aio_kernel_() interface") from
the aio-direct tree interacting with commit 8bc92afcf7f5 ("aio: Kill
unneeded kiocb members") from the aio tree.
I applied the following merge fix patch (and I can carry it as necessary
- thanks, Dave, for the hint patches):
