[PATCH] remove NFS client internal dependence on page->index
This makes the NFS client copy the page->index field into its read and
write request structures (struct nfs_page) when setting up I/O on a
page. this makes it possible for NFS direct I/O support to reuse
existing NFS client subroutines, and helps eventually allow NFS I/O to
and from anonymous pages. it is a prerequisite for NFS direct I/O
support.
