Author: marius Date: Sun Aug 28 11:49:53 2011 New Revision: 225229 URL: http://svn.freebsd.org/changeset/base/225229 Log: Since r221218 rman_manage_region(9) actually honors rm_start and rm_end which may cause problems when these contain garbage so zero the range descriptors embedding the rmans when allocating them.
