Author: mav Date: Thu May 8 08:24:08 2014 New Revision: 265656 URL: http://svnweb.freebsd.org/changeset/base/265656 Log: MFC r263979 (by trasz): Hide CTL messages about SCSI error responses. Too many users take them for actual target errors. They can be enabled back by setting kern.cam.ctl.verbose=1, or booting with bootverbose.
