SubjectRe: [patch] change WARN_ON back to "BUG: at ..."

well - a WARN_ON() can be /anything/. It is the same as BUG_ON(), but it
doesnt crash the box immediately and on purpose. In that sense all
existing BUG_ON()s should be converted to WARN_ON()s or to panic()s
(whichever fits best for that particular BUG_ON()).

[ or all WARN_ON()s should be converted to BUG_ON()s and the behavior of
BUG_ON() should be changed to /not/ crash the system on purpose - and
for those cases where we really do not want to continue, panic()
should be used. That way the user can set panic policy himself. ]

i can whip up a patch for any of these conversions, but i dont think we
need this flux right now.
