Hi Jens,

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

fs/ocfs2/file.c: In function 'ocfs2_sync_file':
fs/ocfs2/file.c:191: error: 'BLKDEV_IFL_WAIT' undeclared (first use in this function)
fs/ocfs2/file.c:191: error: too many arguments to function 'blkdev_issue_flush'

Caused by commit dd3932eddf428571762596e17b65f5dc92ca361b ("block: remove
BLKDEV_IFL_WAIT") interacting with commit
04eda1a18019bb387dc7e97ee99979dd88dc608a ("ocfs2: Flush drive's caches on
fdatasync") that entered Linus' tree before v2.6.36-rc4.

I have used the block tree from next-20100916 for today.
