After looking over all the patches I really thing we should be passing
struct xfs_buf_vec arguments to the functions, and provide a helper
to convert struct xfs_bmbt_irec to the callers.  That avoids having to
add the XFS_EXT_DADDR hack, and keeps the amount of data structures
used in the buffer cache small.
