Author: mav Date: Fri Jun 10 09:18:43 2011 New Revision: 222921 URL: http://svn.freebsd.org/changeset/base/222921 Log: MFC r222652: Update disk's stripesize and stripeoffset parameters on provider open. They are media-dependent and may change in run-time, same as sectorsize and/or mediasize. SCSI devices return physical sector size and offset via READ CAPACITY(16) command and so can not report it until media inserted or at least until probe sequence completed. UNMAP support is also reported there.
