@Neil, @Jeff, could you please look at:
https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/log/?h=vfs.all

and specifically at the merge conflict resolution I did for:

https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/commit/?h=vfs.all&id=f28c9935f78bffe6fee62f7fb9f6c5af7e30d9b2

and tell me whether it all looks sane?
