Hi Christoph,

Thanks for the link. I'm very pleased to see you're working on the
multi-page write and iomap stuff. I'd like to see these patches go
forward and I'll build my fiemap stuff off of them.

Does it make sense to split the first two vfs-related patches from the
others that are more xfs related? I didn't see these patches appear on
linux-fsdevel or lkml, so I assume they're only on the xfs list currently?

It would be nice to see them on linux-fsdevel, since I'm not subscribed to
that xfs list. It would also be useful to get them into some place more
central like Al's vfs tree.
