Hi all,

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

ERROR: modpost: "security_file_ioctl" [fs/overlayfs/overlay.ko] undefined!

Caused by commit

  b5940870e166 ("ovl: call secutiry hook in ovl_real_ioctl()")

I have applied this patch for today.
