Description

FreeBSD update https://svnweb.freebsd.org/base?view=revision&revision=r300866

If the I/O offset and length is multiple of the media size then directly pass the request otherwise use a buffer that is a multiple of the media size. This speeds up I/O quite a bit when using large transfer sizes on 4Kn disks etc.
