Description

These two functions are stubbed out in the client libraries and always just return -1. Wire them into the backend infrastructure that ceph_preadv and ceph_pwritev are using. One challenge is that these functions return int64_t, but the lower level functions seem to pass around ints. This will require a type-safety cleanup as well.

This is mostly needed to support nfs-ganesha which is adding support for vectorized read/write.
