Author: nwhitehorn Date: Tue Oct 11 13:19:56 2011 New Revision: 226250 URL: http://svn.freebsd.org/changeset/base/226250 Log: MFC r226161: Avoid magicking into existence sub-partitions due to leftover blocks when creating new ones by destroying any geom that may have come into existence immediately after adding a partition. The EBR partition scheme is particularly enthusiastic about false positives in this case.
