In my personal option the latest patch posted and described at the following like is a very good candidate for commit: http://docs.FreeBSD.org/cgi/mid.cgi?47AA43B9.1040608 It might have a couple of style related issues, but it should improve things a bit even if some larger VM/VFS/GEOM issues remain. And by the way, a patch from the following PR would be a good "side-dish" for the above patch: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/78987 I think it is simple and obvious enough. -- Andriy Gapon
