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 (powerpc
ppc64_defconfig) failed like this:

fs/fat/file.c: In function 'fat_file_release':
fs/fat/file.c:166:20: error: 'struct dentry' has no member named 'd_count'
      filp->f_dentry->d_count == 1)
                    ^

Caused by commit ff121b02f7e3 ("fat: additions to support fat_fallocate")
from the akpm-current tree interacting with commit  98474236f72e ("vfs:
make the dentry cache use the lockref infrastructure") from Linus' tree.

I don't know if it is safe to read d_lockref.count without locking, and
it is late in the day, so I have just reverted that commit from the
akpm-current tree for today (along with
"fat-additions-to-support-fat_fallocate-fix").

Cheers,
