Subjectlinux-next: build failure after merge of the xfs tree
Hi all,

After merging the xfs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/xfs/xfs_file.c: In function 'xfs_file_dio_aio_write':
fs/xfs/xfs_file.c:744:8: warning: passing argument 1 of 'mapping->a_ops->direct_IO' makes pointer from integer without a cast
ret = mapping->a_ops->direct_IO(WRITE, iocb, &data, pos);
^
fs/xfs/xfs_file.c:744:8: note: expected 'struct kiocb *' but argument is of type 'long long unsigned int'
fs/xfs/xfs_file.c:744:8: warning: passing argument 2 of 'mapping->a_ops->direct_IO' from incompatible pointer type
fs/xfs/xfs_file.c:744:8: note: expected 'struct iov_iter *' but argument is of type 'struct kiocb *'
fs/xfs/xfs_file.c:744:8: warning: passing argument 3 of 'mapping->a_ops->direct_IO' makes integer from pointer without a cast
fs/xfs/xfs_file.c:744:8: note: expected 'loff_t' but argument is of type 'struct iov_iter *'
fs/xfs/xfs_file.c:744:8: error: too many arguments to function 'mapping->a_ops->direct_IO'

So, my merge resolution was not sufficient :-(

Commit 22c6186ecea0 ("direct_IO: remove rw from a_ops->direct_IO()")
removed the first argument from ->direct_IO(), so I added the following
merge fix patch.
