Author: mav Date: Mon Oct 5 07:40:18 2015 New Revision: 288702 URL: https://svnweb.freebsd.org/changeset/base/288702 Log: MFC r281531 (by asomers): Initialize async_arg_ptr in xpt_async when called with async_code AC_ADVINFO_CHANGED. Without this change, newly inserted hard disks won't always have their physical path device nodes created. The problem reproduces most readily when attaching a large number of disks at once.
