Hi Al,

this series cleans up how we implement the various vectored read and write
syscalls, as well as the internal iov_iter based APIs.  It then switches
nfsd to use vfs_iter_read/write which cleans up nfsd.  Note that all
exportable file systems already implement ->read_iter and ->write_iter
anyway.
