- 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. Reviewed by: nathanw, ken, kib Approved by: re Obtained from: Netflix
