Author: dchagin Date: Fri Apr 17 16:42:57 2009 New Revision: 191210 URL: http://svn.freebsd.org/changeset/base/191210 Log: Merge r190708 from HEAD to stable/7: Fix KBI breakage by r190520 which affects older linux.ko binaries: 1) Move the new field (brand_note) to the end of the Brandinfo structure. 2) Add a new flag BI_BRAND_NOTE that indicates that the brand_note pointer is valid. 3) Use the brand_note field if the flag BI_BRAND_NOTE is set and as old modules won't have the flag set, so the new field brand_note would be ignored.
