I finally sorted it out: a checkout with -rnetbsd-7 but at some time
src/sys/fs/puffs was cleared and checked out from -current, resulting in
an hybrid kernel. The difference is thin, just a few lines, but of
course a cvs diff would not tell it since it silently compared the tree
to netbsd-7 and a directory to HEAD.

Hence in the end, no bug to fix, it was a developer PEBKAC. But
LOCKDEBUG_BARRIER raised a real problem.
