Author: imp Date: Wed Feb 21 15:57:36 2018 New Revision: 329725 URL: https://svnweb.freebsd.org/changeset/base/329725 Log: Consolidate three copies of ZFS commands into a central location. There's no reason to have multiple copies of lszfs and reloadbe. Consolidate them into one location. Also ldi_get_size is the same everywhere (except sparc64). Make it the same everywhere as the common definition is more general and will work on spar64.
