Well, I had that in one version of the patch, but people didn't think
it would be useful. Maybe you'd like to check out Oliver's comments
at http://marc.theaimsgroup.com/?l=linux-kernel&m=102644431806734&w=2
and respond? If there's demand for MUST_NOT_HOLD, I'd be happy to add
it since it should be easy. But if you're using it to enforce lock
ordering as Oliver suggests, then there are probably more robust
solutions.
Thanks,
Jesse
