Subject: linux-next: build failure after merge of the akpm-current tree

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

fs/ocfs2/aops.c: In function 'ocfs2_direct_IO_write':
fs/ocfs2/aops.c:784:9: error: too few arguments to function 'blkdev_issue_zeroout'
   ret = blkdev_issue_zeroout(osb->sb->s_bdev,
         ^
In file included from fs/ocfs2/aops.c:31:0:
include/linux/blkdev.h:1165:12: note: declared here
 extern int blkdev_issue_zeroout(struct block_device *bdev, sector_t sector,
            ^

Caused by commit e95f8b5356c4 ("ocfs2: implement
ocfs2_direct_IO_write") interacting with commit d93ba7a5a97c ("block:
Add discard flag to blkdev_issue_zeroout() function") from the block
tree.

I have added this merge fix patch:
