Author: scottl Date: Tue Sep 24 16:50:53 2013 New Revision: 255853 URL: http://svnweb.freebsd.org/changeset/base/255853 Log: Update the CAM API for FreeBSD 10: - Remove the timeout_ch field. It's been deprecated since FreeBSD 7.0; MPSAFE drivers should be managing their own timeout storage. The remaining non-MPSAFE drivers have been modified to also manage their own storage, and should be considered for updating to MPSAFE (or removal) during the FreeBSD 10.x lifecycle. - Add fields related to soft timeouts and quality of service, to be used in upcoming work. - Add room for more flags in the CCB header and path_inq structures. - Begin support for extended 64-bit LUNs. - Bump the CAM version number to 0x18, but add compat shims. Tested with camcontrol and smartctl.
